Dear all
I have a list containing 150 simulated datasets in R. Is there a way to
convert it to the Stata format such that I will be able to apply some Stata
functions on each dataset in the list?

First thanks for the help for an earlier question about error handling!
I have problem filtering a dataset.
I 'm trying to filter the data in the y columns based on the values in the x
column
hi all
a very simple question once again!!!
can we change the "y " range in a histogram?
e.g.
x rnorm(1000)
hist(x ylim 0.5 prob T) #this does not work
any suggestions???

I am trying to replicate some multilevel models with binary outcomes
using R 's "lmer " and "glmmPQL " and Stata 's gllmm respectively.

I am wondering how to test whether a simple linear regression model

Thanks.
