In R - How to use spml objects in Stargazer
Since stargazer does not work with splm models, I tried texreg, as suggested in the post above. basically these is what I do:
library(spdep)
library(texreg)
fm<-Y ~ x+m+s+slag(x,listw=w.listw) #formula to be applied
#Model1- 1st Spatial RE model
m1 <- spml(formula=fm, data = spatialpaneldata,listw = w.listw, model="random", spatial.error="b", lag=T)
#Model2 - 2nd Spatial RE model
m2<- spml(formula=fm, data = spatialpaneldata,listw = w.listw, model="random", spatial.error = "kkp", lag=T)
then I apply texreg to get a nice table results output for my paper
texreg(list(m, m2), dcolumn = TRUE, booktabs = TRUE,use.packages = FALSE, label = "tab:3", caption = "Two spatial models.",float.pos = "hb!")
however, i get the error below:
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘extract’ for signature ‘"splm"’
>
How can I make (extract) texreg applicable to spatial panel models, or splm models?
I hope I can get some help..

I've already trained several models for a binary classification problem, basing my election on F-Score and AUC. The code used has been the following:
svm = StandardScaler()
svm.fit(feat_train)
feat_train_std = svm.transform(feat_train)
feat_test_std = svm.transform(feat_test)
model_10= BalancedBaggingClassifier(base_estimator=SVC(C=1.0, random_state=1, kernel='linear'),
sampling_strategy='auto',
replacement=False,
random_state=0)
model_10.fit(feat_train_std, target_train)
pred_target_10 = model_10.predict(feat_test)
mostrar_resultados(target_test, pred_target_10)
pred_target_10 = model_10.predict_proba(feat_test)[:, 1]
average_precision_10 = average_precision_score(target_test, pred_target_10)
precision_10, recall_10, thresholds = precision_recall_curve(target_test, pred_target_10)
auc_precision_recall_10 = auc(recall_10, precision_10)
disp_10 = plot_precision_recall_curve(model_10, feat_test, target_test)
disp_10.ax_.set_title('Binary class Precision-Recall curve: '
'AUC={0:0.2f}'.format(auc_precision_recall_10))
Afterwards, I load the model as follows:
modelo_pickle = 'modelo_pickle.pkl'
joblib.dump(model_10,modelo_pickle)
loaded_model = joblib.load(modelo_pickle)
Then, the aim is to load a new dataset, which columns are the same as the model's variables, and make a prediction for each line:
lista_x=x.to_numpy().tolist()
resultados=[]
for i in lista_x:
pred = loaded_model.predict([i])
resultados.append(pred)
print(resultados)
However, every single result is equal to 1, which does not make any sense. Would anyone tell me what am I missing, please?
Thank you in advance.

Previously described.
I am using a data set called sleep (found here: https://drive.google.com/file/d/15ZnsWtzbPpUBQN9qr-KZCnyX-0CYJHL5/view) to run a three way within subject ANOVA comparing Performance based on Stimulation, Deprivation, and Time. I have successfully done this before using anova_test from rstatix. I want to look at the sphericity output but it doesn't appear in the output. I have got it to come up with other three way within subject datasets, so I'm not sure why this is happening. Here is my code:
anova_test(data = sleep, dv = Performance, wid = Subject, within = c(Stimulation, Deprivation, Time))
I also tried to save it to an object and use get_anova_table, but that didn't look any different.
sleep_aov <- anova_test(data = sleep, dv = Performance, wid = Subject, within = c(Stimulation, Deprivation, Time))
get_anova_table(sleep_aov, correction = "GG")
This is an ideal dataset I pulled from the internet, so I'm starting to think the data had a W of 1 (perfect sphericity) and so rstatix is skipping this output. Is this something anova_test does?
Here also is my code using a dataset that does return Mauchly's:
weight_loss_long <- pivot_longer(data = weightloss, cols = c(t1, t2, t3), names_to = "time", values_to = "loss")
weight_loss_long$time <- factor(weight_loss_long$time)
anova_test(data = weight_loss_long, dv = loss, wid = id, within = c(diet, exercises, time))
Not an expert at all, but it might be because your factors have only two levels.
From anova_summary() help:
"Value
return an object of class anova_test a data frame containing the ANOVA table for independent measures ANOVA. However, for repeated/mixed measures ANOVA, it is a list containing the following components are returned:
ANOVA: a data frame containing ANOVA results
Mauchly's Test for Sphericity: If any within-Ss variables with more than 2 levels are present, a data frame containing the results of Mauchly's test for Sphericity. Only reported for effects that have more than 2 levels because sphericity necessarily holds for effects with only 2 levels.
Sphericity Corrections: If any within-Ss variables are present, a data frame containing the Greenhouse-Geisser and Huynh-Feldt epsilon values, and corresponding corrected p-values. "
Sometimes JavaScript is playing with me (although the deal was that I would be playing with it...) This test code below keeps resisting so I'm looking for a little help from more clever people around here.
Answering to a recent question I tried to create a readable list of all the color IDs useable in Google Advanced Calendar API.
The request is very simple : Calendar.Colors.get()
The response is an object with a couple of properties, each one being other objects with other properties.
I can go down to the second level but the last -and most useful in this case - level returns a disturbing "undefined" (see partial log below)
And that's my question...
code with comments :
function getColorList(){
var colors = Calendar.Colors.get();
//Logger.log(JSON.stringify(colors));
for(var cat in colors){
Logger.log("category "+cat+" = "+JSON.stringify(colors[cat])+'\n\n')
}
// from there I try the "event" category
var events = colors["event"];
Logger.log('object colors["event"] = '+ JSON.stringify(events))
// then I try to get every properties in this object
for(var val in events){
Logger.log("key "+val+" = "+JSON.stringify(events[val]))
}
}
Full log is viewable here (externalized to keep this reasonably short)
Looks like (key) may be indicating a read-only definition as Sandy was eluding to.
Just make your own object from colors to loop through after converting it to string:
var json = JSON.stringify(colors["event"]);
var myObj = JSON.parse(json);
for(var val in myObj){
Logger.log("key "+ val +" = "+JSON.stringify(myObj[val]))
}
I working with Database first C# MVC, EF6, LINQ and JSon to try and pass data to both Highcharts and Google Maps for some of my reporting.
If I could add an image I would show you the relevant portion of my model, but sadly I need more reputation to do that...
The portion of the Entity Model I'm concentrating on right now is based on a central Docket that contains a BuildingCode as part of a one-to-many relationship to a building with and address and further relationship to the buildings polygons (for mapping). Dockets are also classified by one or more DocketTypes and thus there is a many-to-many relationship between Dockets and DocketTypes, which is not directly exposed to through the EF.
As an example a Docket which represents an investigation, could be related to the theft of a mobile phone in building A located on Campus X, not only was the cellphone stolen but the assailant also assaulted the victim in order to steal the mobile phone. So there are 2 DocketTypes here 1. Theft of mobile phone and 2. assault. Note: this is fictitious and for illustration purposes only .
One of my fundamental reports requires that I count how many docketTypes affect each building and each campus in a given period. When I display this I also need to show what the DocketTypes are.
I have no end of nightmare trying to find a way to get this right, I keep running into circular reference errors and needing to use explicit conversions when trying to model the data with LINQ so that I can pass a single nested object through JSON to the client side where displaying will occur.
In the below code I am told I need an Explicit conversion:
Cannot implicitly convert type 'Campus_Investigator.ViewModels.DocketTypeViewModel' to 'System.Collections.Generic.IEnumerable<Campus_Investigator.ViewModels.DocketTypeViewModel>'. An explicit conversion exists (are you missing a cast?)
var currentDocketQuery = from d in db.Dockets
from dt in d.DocketTypes
from bp in d.BuildingDetail.BuildingPolygons
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = new DocketTypeViewModel()
{
Category = dt.Category,
SubCategory = dt.SubCategory,
ShortDescription = dt.ShortDescription
}
};
I appreciate any ideas on how I can explicitly convert this or is that a better method I can use and avoid the circular reference error?
You included some redundant part in your query (which performs some inner join). The from bp in d.BuildingDetail.BuildingPolygons is joined in but then is not shown in the result. So it totally does not make sense. There may be duplicated elements in the result due to that. The from dt in d.DocketTypes is wrong joined in, although you need it in the result but because the DocketTypes is output per d in db.Dockets, so it's just simply queried like this:
var currentDocketQuery = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = d.DocketTypes
};
In fact I can see the commented line //BuildingPolygons = d.BuildingDetail.BuildingPolygons, so if you want to include that, it should also work.
If the DocketTypes has different type of d.DocketTypes, then you need a simple projection like this:
var currentDocketQuery = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = d.DocketTypes.Select(e => new DocketTypeViewModel()
{
Category = e.Category,
SubCategory = e.SubCategory,
ShortDescription = e.ShortDescription
})
};
I managed to solve this one by using the below. The major hassle with this is the circular referencing that exists in the model. When JSON serializes these, everything falls apart so it takes a lot of transforming to make sure that I only extract what I need. In this case grouped campus and building data (below includes the polygons which where only half commented out in the above) and then the include the detail of the DocketTypes that occurred at each building.
var datetime = DateTime.Now.AddDays(-30);
var campusDocket = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
group d by new { d.BuildingDetail.CampusName, d.BuildingDetail.BuildingCode, d.BuildingDetail.BuildingName } into groupdata
select new CampusBuildingDocketTypeViewModel
{
BuildingCode = groupdata.Key.BuildingCode,
BuildingName = groupdata.Key.BuildingName,
CampusName = groupdata.Key.CampusName,
Count = groupdata.Count(),
BuildingPolygons = from bp in db.BuildingPolygons
where bp.BuildingCode == groupdata.Key.BuildingCode
select new BuildingPolygonViewModel
{
Accuracy = bp.Accuracy,
BuildingCode = bp.BuildingCode,
PolygonOrder = bp.PolygonOrder,
Latitude = bp.Latitude,
Longitude = bp.Longitude
},
DocketTypes = from doc in db.Dockets
from dt in doc.DocketTypes
where doc.OccurrenceStartDate >= datetime && doc.BuildingCode == groupdata.Key.BuildingCode
select new DocketTypeViewModel
{
Category = dt.Category,
SubCategory = dt.SubCategory,
ShortDescription = dt.ShortDescription
}
};
The Answer again is ViewModels. I'm finding ViewModels seem to solve a lot of problems...
I am joining a table to an in memory list and wanting to create an anonymous type from the results. I have joined the 2 data sources together ok, but I'm not sure of the syntax required to use a property from the in memory list in the anonymous type.
Here's my code
public DataKeys(IEnumerable<Element> elements)
{
var defsource = new DefinitionSource();
var items = from def in defsource.Definitions
where elements.Select(el=> el.Value).Contains(def.Name)
select new { def.Key };
...
}
(Obviously "elements" is an in-memory list of element and "DefinitionSource" is a wrapper around a table.) This works fine, but as you can see there is no property from the in-memory list of elements. I've tried this
var items = from def in defsource.Definitions
where elements.Select(el=> el.Value).Contains(def.Name)
from el in elements
where el.Value.Equals(def.Name)
select new { el.NodeType, def.Key };
but at run time it gens a "{"Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operator."}"
So what is the syntax I need to do this?
Many thx IA
Simon
This might help:
var def=defsource.Definitions
.Where(a=>elements.Select(el=>el.Value).Contains(a.Name))
.ToList();
var items = from d in def
from el in elements
.Where(a=>a.Value==d.Name)
select new { el.NodeType, d.Key };
To query over two data sources both of them needs to be in memory are both of them should be in database. you can do the following to achieve the results you want
var query = (from def in defsource.Definitions
where elements.Select(el=> el.Value).Contains(def.Name)
).ToList();//bring filtered result in memory
var Items = from def in query //Definitions are already filtered no need to re-apply where
from el in elements.Where(a=>a.Value == def.Name)
select new {el.NodeType, def.Key};
