Models for Sample Selection Bias 来自 Semantic Scholar 喜欢 0 阅读量: 144 作者: WRD Mare 摘要: When observations in social research are selected so that they are not independent of the outcome variables in a study, sample selection leads to biased inferences about social processes. Nonrandom ...
Finally, Heckman models account for sample-induced endogeneity, but are not effective when other sources of endogeneity are present . Managerial summary: When nonrandom samples are used to test statistical relationships, sample selection bias can lead researchers to flawed conclusions ...

Polychotomous sample selection models include multinomial choice models and models with multiple rules for sample inclusion. The author analyzes two standard parametric approaches to selectivity bias correction in such models - the Lee and Generalized Heckman (GH) methods. The paper's main point is ...

Experiments with simulated data confirm that this method avoids bias due to feature selection. We also apply the naive Bayes model to subsets of data relating gene expression to colon cancer, and find that correcting for bias from feature selection does improve predictive performance.Li, L; Zhang...
This trend does not suggest that more complex models like the BB-NB N-mixture model were “true” for our data, and that it was therefore wrong to use a simpler model for low-information datasets, since in fact simpler models minimize out-of-sample prediction error in lower-information ...
