Model Developmet

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?

Re: Model Developmet

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.
