st: mi impute chained

Hello Statalist,

I am in the process of mi impute chained approach for missing data.  

Because I have a number of variables that I need to impute (the data is
longitudinal and in wide format), I am attempting mi impute on an initial
group of variables.

I first attempted to check my models for convergence outside of the mi
impute chained command. 

But I received an error message option noomit not allowed.

Stata help indicates there is a syntax problem.

I have two questions. First, should I throw all the variables into one
model.

Second, what does  option noomit indicate?

Thanks for your assistance. Output is below.
