GMM error message

[lilyjiang]

Hi,

We try to run GMM model but it gave us error message as follows:

At 2SLS Iteration 0 there are 0 missing observations available. At least 22 are needed to compute the next iteration.

What does it mean? how to solve the problem?

thanks,

Lily

Hi Lily,

Can you provide some additional information?

Which procedure are you using?

Can you share the syntax and information about the data set?

thanks-Ken
