The ESETRAN Stata module helps transform estimates and standard errors in parmest resultssets. It takes user-specified variables with estimates and standard errors, applies a transformation, and updates them to double precision if needed. It ensures parameter values at boundaries are set to appropriate values. By using the parmcip option, users can recalculate statistics and confidence limits for transformed parameters, allowing for asymmetric confidence intervals. This is particularly useful for scenarios like logistic regression where symmetric intervals need to be adjusted for correct coverage probability.
