Hi,

I am just wondering if you could give me two answere to some very simple questions tabout the ordered logit model:

1) When exactly should a Wald test be used as opposed to a t-test?
2) I have run an ordered logit analysis on my data. For one of my independent variables,which has 4 categories, two out of 4 categories seem to be non-significant. Does this mean that I have to drop the whole variiable from the analysis or can I just take out the non-significant categories?

Thanks,

Ale

I am a grad student at Harvard attempting to use the VARLAG module.
Unfortunately, when I try to use it, even when I use the example data set
you provided, I always get the same reply:

if not allowed
r(101);


What am I doing wrong?  Any help would be greatly appreciated.

Sincerely,
Michael Horowitz
