I am getting the same value for the regression coefficient of a predictor if I fix the intercept/threshold term at 0 and when I don't when I fit a simple probit model to data I've generated (so I know the true values). This does not happen with a logit model. Is there a reason for this? I would think they should change. If I fit the same model with Splus I get different results. My model is:
results for the "z" parameter are the same with this:
y on z*0.3;
[y$1@0];
and this:
y on z*0.3;
using THETA parameterization.
