Valid Post-Selection Inference
It is common practice in statistical data analysis to perform data-driven variable selection and derive statistical inference from the resulting model. Such inference enjoys none of the guarantees that classical statistical theory provides for tests and confidence intervals when the model has been chosen a priori. We propose to produce valid “post-selection inference” by reducing the problem to...
متن کاملValid Post-Selection and Post-Regularization Inference: An Elementary, General Approach
Here we present an expository, general analysis of valid post-selection or post-regularization inference about a low-dimensional target parameter, α, in the presence of a very high-dimensional nuisance parameter, η, which is estimated using modern selection or regularization methods. Our analysis relies on high-level, easy-to-interpret conditions that allow one to clearly see the structures nee...

It is common practice in statistical data analysis to perform datadriven variable selection and derive statistical inference from the resulting model. Such inference enjoys none of the guarantees that classical statistical theory provides for tests and confidence intervals when the model has been chosen a priori.

متن کاملPost - Selection Inference Online Appendix
B.1 The Full Model Interpretation of Parameters. In the full model interpretation, coefficients always have the fixed meaning as full model parameters. Variable selection then means setting some coefficient estimates to zero, and these estimates always exist for all predictors, irrespective of whether they are selected or deselected. The full model interpretation of parameters is appropriate, f...
