Statistical methods/details for confidence interval for probit models with an interaction term

Jun 3, 2024 12:54 PM (348 views)

Hello, 

 

I fitted a probit model with an interaction term by using the Fit Model platform and specifying the 

Effects( A, B, A*B ), where :A is a continuous variable and B is a dichotomous variable. In the parameter estimates section I got the Lower CLs and Upper CIs for the intercept, A, B, A*B. terms, respectively. Could you provide some details about how the confidence intervals are calculated for them (intercept, A, B, and A*B )? 

 

Also, for a typical linear regression model (unrelated to my above scenario) fitted using the Fit Model platform, how are the confidence intervals in the parameter estimates section calculated. 

 

Thanks!

 

Best,

Li
