The Sample Selection Model from a Method of Moments Perspective — Dec 31, 2006

It is shown how the usual two-step estimator for the standard sample selection model can be seen as a method of moments estimator. Furthermore, it is shown that from the MM formulation, it is straightforward to derive various specification tests, in particular tests for selection bias, equivalence with the censored regression model, normality, homoskedasticity, and exogeneity.

JOURNAL ARTICLE

Imputation of SF-12 Health Scores for Respondents with Partially Missing Data — Dec 31, 2004

Missing SF-12 items are prevalent and lead to reduced analytical power. Regression-based multi-pattern imputation using the available SF-12 items is efficient and can produce good estimates of the scores.
