Model Developmet

[Moh]

Hi Folks - I tried to develope a model using glimmix procedure. 

However, the t-value of some coefficients is M or I. Do you have any idea why and how can I fix the problem?

Thanks

Note that the standard errors in those cases is 0, so the calculation will involve division by 0. 

Without your data, it's impossible to say what is causing this, but it could be perfect collinearity, I think.
