[R] Archer-Lemeshow Goodness of Fit Test for Survey Data with Log. Regression

?Thank you, Anthony.  Your approach does work; however, I am concerned to some
degree about subsetting the data prior to creating the new svrepdesign as I know
that it is not recommended to subset the data prior to creating the svrepdesign
object.  I am not sure if this is a significant concern in this context as the
model was fitted with the original svrepdesign that was created prior to
subsetting any data and the new svrepdesign is being used to run the diagnostic
for the model.  Any thoughts on that issue?

Also, from my understanding of the outcome of the diagnostic, low p values
indicate a poor model fit.

Sincerely,

Courtney

great minimal reproducible example, thanks.  does something like this work?

?Hello R Experts,

I am trying to implement the Archer-Lemeshow GOF Test for survey data on a
logistic regression model using the survey package based upon an R Help Archive
post that I found where Dr. Thomas Lumley advised how to do it:
http://r.789695.n4.nabble.com/Goodness-of-t-tests-for-Complex-Survey-Logistic-Regression-td4668233.html

Everything is going well until I get to the point where I have to add the
objects 'r' and 'g' as variables to the data frame by either
using the transform function or the update function to update the svrepdesign
object.  The log. regression model involved uses a subset of data and some of
the values in the data frame are NA, so that is affecting my ability to add
'r' and 'g' as variables; I am getting an error because I only
have 8397 rows for the new variables and 16197 in the data frame and svrepdesign
object.  I am not sure how to overcome this error.

hi, my code does not subset the survey design on the line that creates the
svrepdesign().  subsetting in order to create a variable while your data is
still a data.frame is probably okay, so long as you expect the observations
outside of the subset to be NAs like they are in this case.

[R] Archer-Lemeshow Goodness of Fit Test for Survey Data with Log. Regression

Like I had said, I was concerned with the low p value outcome of this diagnostic
test, so I went on to test other interactions that I had not previously tested. 
I did find an interaction that is significant.  Now when I go to run the
diagnostic to check for any improvement, I am coming up with an error.

##Testing with interaction model
allCCI12 <-
svyglm(formula=F3ATTAINB~F1PARED+BYINCOME+F1RACE+F1SEX+F1RGPP2+F1HIMATH+F1RTRCC+F1HIMATH*F1RGPP2,family="binomial",design=elsq1ch_brr,subset=BYSCTRL==1&G10COHRT==1,na.action=na.exclude)
summary(allCCI12)

r <- residuals(allCCI12, type="response")
f<-fitted(allCCI12)
your_g<- cut(f, c(-Inf, quantile(f,  (1:9)/10, Inf)))

elsq1ch[ elsq1ch$BYSCTRL==1&elsq1ch$G10COHRT==1 , 'your_g' ] <-
your_g
elsq1ch[ elsq1ch$BYSCTRL==1&elsq1ch$G10COHRT==1 , 'r' ] <- r
newdesign<-svrepdesign(variables = elsq1ch, repweights = elsq1ch[,18:217],
weights = elsq1ch[,17], combined.weights = TRUE, type = "BRR")

decilemodel<- svyglm(r~your_g,
design=newdesign,subset=BYSCTRL==1&G10COHRT==1)

great minimal reproducible example, thanks.  does something like this work?



#Log. Reg. model-all curric. concentrations including F1RTRCC as a predictor
allCC <-
svyglm(formula=F3ATTAINB~F1PARED+BYINCOME+F1RACE+F1SEX+F1RGPP2+F1HIMATH+F1RTRCC,family="binomial",design=elsq1ch_brr,subset=BYSCTRL==1&G10COHRT==1,na.action=na.exclude)
summary(allCC)

r <- residuals(allCC, type="response")
f<-fitted(allCC)
your_g<- cut(f, c(-Inf, quantile(f,  (1:9)/10, Inf)))

elsq1ch[ elsq1ch$BYSCTRL==1&elsq1ch$G10COHRT==1 , 'your_g' ] <-
your_g
elsq1ch[ elsq1ch$BYSCTRL==1&elsq1ch$G10COHRT==1 , 'r' ] <- r
newdesign<-svrepdesign(variables = elsq1ch, repweights = elsq1ch[,18:217],
weights = elsq1ch[,17], combined.weights = TRUE, type = "BRR")

decilemodel<- svyglm(r~your_g,
design=newdesign,subset=BYSCTRL==1&G10COHRT==1)
regTermTest(decilemodel, ~your_g)

?Hello R Experts,

I am trying to implement the Archer-Lemeshow GOF Test for survey data on a
logistic regression model using the survey package based upon an R Help Archive
post that I found where Dr. Thomas Lumley advised how to do it:
http://r.789695.n4.nabble.com/Goodness-of-t-tests-for-Complex-Survey-Logistic-Regression-td4668233.html

Everything is going well until I get to the point where I have to add the
objects 'r' and 'g' as variables to the data frame by either
using the transform function or the update function to update the svrepdesign
object.  The log. regression model involved uses a subset of data and some of
the values in the data frame are NA, so that is affecting my ability to add
'r' and 'g' as variables; I am getting an error because I only
have 8397 rows for the new variables and 16197 in the data frame and svrepdesign
object.  I am not sure how to overcome this error.

The following is a MRE:

##Archer Lemeshow Goodness of Fit Test for Complex Survey Data with Logistic
Regression

library(RCurl)
library(survey)

data <-
getURL("https://raw.githubusercontent.com/cbenjamin1821/careertech-ed/master/elsq1adj.csv")
elsq1ch <- read.csv(text = data)

#Specifying the svyrepdesign object which applies the BRR weights
elsq1ch_brr<-svrepdesign(variables = elsq1ch[,1:16], repweights =
elsq1ch[,18:217], weights = elsq1ch[,17], combined.weights = TRUE, type =
"BRR")
elsq1ch_brr

##Resetting baseline levels for predictors
elsq1ch_brr <- update( elsq1ch_brr , F1HIMATH = relevel(F1HIMATH,"PreAlg
or Less") )
elsq1ch_brr <- update( elsq1ch_brr , BYINCOME =
relevel(BYINCOME,"0-25K") )
elsq1ch_brr <- update( elsq1ch_brr , F1RACE =
relevel(F1RACE,"White") )
elsq1ch_brr <- update( elsq1ch_brr , F1SEX = relevel(F1SEX,"Male")
)
elsq1ch_brr <- update( elsq1ch_brr , F1RTRCC =
relevel(F1RTRCC,"Academic") )

#Log. Reg. model-all curric. concentrations including F1RTRCC as a predictor
allCC <-
svyglm(formula=F3ATTAINB~F1PARED+BYINCOME+F1RACE+F1SEX+F1RGPP2+F1HIMATH+F1RTRCC,family="binomial",design=elsq1ch_brr,subset=BYSCTRL==1&G10COHRT==1,na.action=na.omit)
summary(allCC)

#Recommendations from Lumley (from R Help Archive) on implementing the Archer
Lemeshow GOF test
r <- residuals(allCC, type="response")
f<-fitted(allCC)
g<- cut(f, c(-Inf, quantile(f,  (1:9)/10, Inf)))

# now create a new design object with r and g added as variables
#This is the area where I am having problems as my model involves a subset and
some values are NA as well
#I am also not sure if I am naming/specifying the new variables of r and g
properly
transform(elsq1ch,r=r,g=g)
elsq1ch_brr <- update(elsq1ch_brr,tag=g,tag=r)
#then:
decilemodel<- svyglm(r~g, design=newdesign)
regTermTest(decilemodel, ~g)
#is the F-adjusted mean residual test from the Archer Lemeshow paper

Thank you,
Courtney
