st: xtlsdvc: endogenous vs. predetermined regressors

["Porter, Burt" <rbporter@iastate.edu>]

When estimating a dynamic panel model using xtlsdvc with an unbalanced
panel, is it possible to:

- specify a subset of regressors as predetermined rather than strictly
exogenous?
- specify the maximum lags of the regressors to be used as instruments?

I realize both of these are possible with xtabond2, but am unsure how to
implement with xtlsdvc or the effect on the bias correction.

Thank you in advance

Burt Porter
