Presenting information in a less technical style, this book introduces the origins, statistical foundations, main features, and debates centering on four related models for estimating treatment effects: Heckman's sample selection model, propensity score matching, matching estimators, and PSA with nonparametric regression.
Alternative regression methodologies explored include nonparametric regression, logistic regression, Bayesian regression, robust regression, fuzzy regression, random coefficients regression, regression in a spatial domain, nonlinear least squares, and time- series issues.
