WebThis example demonstrates the use of Hausman’s specification test to analyze the IIA assumption and decide on an appropriate model that provides less restrictive substitution patterns (nested logit or multinomial probit).

Secondly, the usual Hausman contrast test requires one estimator to be efficient under the null hypothesis. If data are heteroskedastic, the least squares estimator is no longer efficient. Options for carrying out a Hausman-like test in this case include estimating an artificial

We’d need something that satisfies C o v ( P, Z) ≠ 0 and C o v ( Z, μ 1) = 0. The trouble with simultaneous equations is that upon observing some ( P, Q) pair, all ...
