8.1.3 Advanced programming to tolerate errors Errors are not only of the typographical kind; some are substantive. A command that is valid in one dataset might not be valid in another. Moreover, in advanced programming, errors are sometimes anticipated: use one dataset if it is there, but ...
PC1 and PC2 can be calculated using estat ic, see estat ic. Notes: The IC and PC are only valid for static panel models. The IC and PC are intended to identify the optimal set of cross-section averages. DO NOT use the criteria to select the number of lags in a dynamic model. ...
