I am estimating two nonlinear models with the “nl” command and would like to compare the results afterwards with “suest”. However, I get the error message “model_1 was estimated with a non-standard vce (gnr)”. 
The sues-help states that the “estimators should be estimated without vce(robust) or vce(cluster clustvar) options. Since I am doing this I am not sure why I get the error.

nl (dep1 = ( {i}^_i) * ({b}^_b) * exp(-1* 0.27 * ({bi}^_i)*({bs}^_s))
estimates store model_1

nl (dep2 = ({i}^_i) * ({b}^_b) * exp(-1* 0.45 * ({bi}^_i)*({bs}^_s))
estimates store model_2

suest model_1 model_2
