Forward orthogonal deviations

WebApr 9, 2024 · The fact that xtabond2 internally applies the forward operator to the instruments can be confusing. To maximize the correlation of the instruments with the regressors, the contemporaneous values should be used (which would require specifying lagged values for the instruments in xtabond2). There is no option in xtdpdgmm to apply … WebThe forward difference formula is a first order scheme since the error goes as the first power of h.

The instruments are not constructed in the way you think they are. For that reason, I would advise against using forward-orthogonal deviations with xtabond2. You can instead use my xtdpdgmm command. cheesecake for a crowd https://higley.org
