I typed the following command:
doLCA any_alcohol any_binge smoking_last_3months folic_acid_first,
nclass(4)
seed(100000) ///
categories(2 2 2 2)
criterion(0.000001)
rhoprior(1.0)
return list
matrix list r(gamma)
matrix list r(gammaSTD)
matrix list r(rho)
matrix list r(rhoSTD)
matrix list r(post_prob)
The returned error was:
matrix r (gammaSTD) not found &
matrix r (rhoSTD) not found
with the following message

To get good answers from people willing to advise, please specify what
you typed on the command line as well as the error messages you
receive.

> I believe this error occurs when you try to run the LCA Stata Plugin from The Methodology Center at Penn State (http://methodology.psu.edu/downloads/lcastata) on binary variables that are coded as 0/1. The data must be positive integers, so you might try to add 1 to any binary variables coded as 0/1 and then attempt to rerun your analysis.

That is necessary due to the maximum matrix size limitations of Stata/IC. If you are using a higher version of Stata, you should set maxiter(5000) or higher.
