<p>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.</p>

<p>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.</p>

<p>Quality improvement programs appear to improve quality of care without increasing disparities, and may offer an approach to reduce health disparities.</p>
