Robust Estimation of Heckman Modelnciples can be used to carry out a robustness analysis in [.] model and how to construct robust versions of Heckman’s two-stage estimator. These are central tools for the statistical analysis of data based on non-random samples from a population.

New Estimation Method for Mixture of Normal Distributions obtain initial estimates of parameters; then upgrade the estimates to better estimates recursively. The initial estimates are simply Method of Moments Estimates in this paper. Empirical results show that parameter estimates are more accurate than that with traditional EM and SEM algorithms.

Why Cannot We Have a Strongly Consistent Family of Skew Normal (and Higher Order) Distributionsution. However, this selection is not strongly consistent in the above sense. In this paper, we show that this absence of strong consistency is not a fault of a specific selection but a general feature of the problem: for third and higher order moments, no strongly consistent selection is possible.
