I have a follow up question on heterogeneous choice models. I am interested in testing which variables significantly predict residual variance. I've tried many configurations of the "sw, pe(.05): oglm y x1 x2 x3 x4, eq2(x1 x2 x3 x4) flip" but have not been able to achieve convergence. Yet, when I use the gologit2 command and the autofit option, the model runs smoothly and I am told which covariates do not meet criteria for parallel line assumptions. I can then run the model using gologit2 and specify which predictors meet the parallel line assumptions and which do not. Is this an appropriate strategy? I am ultimately interested in testing for an interaction in a logistic model.
