I am currently working on this dataset IAMR7DFL.DTA
I am looking forward to use survey weights for the chi-square test and logistic regression. After searching in the internet, I came across this piece of code.
my_design <-svydesign(id=~Mendata$psu, weights=~Mendata$wt, strata=Mendata$strata, data=Mendata, survey.lonely.psu = "adjust")
It worked and my_design shows this
> my_design
Stratified 1 - level Cluster Sampling design (with replacement)
With (9102) clusters.
svydesign(id = ~Mendata$psu, weights = ~Mendata$wt, strata = Mendata$strata,
data = Mendata, survey.lonely.psu = "adjust")
After that when I am doing the chi-square test like this,
I am getting the following error.
> svychisq(~InternetUsage+RuralOrUrban, my_design, statistic="adjWald")
Error in onestrat(x[index, , drop = FALSE], clusters[index], nPSU[index][1], :
Stratum (51) has only one PSU at stage 1
Kindly help me to resolve this issue and also please specify the analysis of chi-square test and logistic regression with and without survey weights.
