<> A preliminary implementation of the Theil-Goldberger 'mixed estimation' routine for regression equations is available from SSC as package tgmixed. N.B.: this very old use of the term 'mixed estimation' has nothing in common with the current usage in, e.g., xtmixed or gllamm. From the help file: tgmixed estimates a regression equation subject to stochastic linear constraints, using the Theil-Goldberger (Int.Ec.Rev., 1961) mixed estimation technique. This estimator is a generalization of cnsreg, which applies exact linear constraints to a regression equation. In the Theil-Goldberger technique, the constraints hold with some degree of subjective belief. The routine computes the Theil compatibility statistic (Theil, JASA 1963) for the null hypothesis that the sample and non-sample information are compatible. Under the null, this statistic is distributed Chi-squared, with degrees of freedom equal to the number of stochastic constraints.
