Hello, I am trying to use tmodel to estimate a demand model with endogenous prices and a random price coefficient. It works, but I have not been able to find the command to produce empirical bayes estimates of the random effects and to put them into a SAS data set. Here is my code:

proc tmodel data=some_data_file outparms=some_output_file;
crosssection upc  ;
endogenous logPrice;
parms a -2
b0 -2
s2u .1;
instruments logpriceInst;
logUnitSales = a + (b0 + b1)*logPrice;
performance nthreads = 8;
random b1 ~ normal(0, s2u);
fit logUnitSales ;

So far, it does create a file with the estimated fixed effects but not the random effects. Thanks in advance.
