 Talk on prediction regions and intervals

 The next preprint provides large sample theory for the elastic net and OLS variable selection, and simplifies large sample theory for ridge regression and lasso. Theory for 3 bootstrap confidence regions is given,
and the coverage should be near the nominal for forward selection.

 The following preprints have been submitted.

 The next preprint gives prediction intervals that can be useful when
the sample size is less than the number of variables. These prediction intervals are useful for comparing shrinkage estimators like forward selection and lasso. Large sample theory for lasso, the elastic net and OLS variable selection is given.

 The next preprint gives bootstrap confidence regions that can be used for
bootstrap tests for OLS variable selection estimators. The tests also simulate well for lasso. Theory for 3 bootstrap confidence regions is given, and the coverage should be near the nominal for forward selection.

 The next preprint needs a lot of work but shows how to get prediction intervals for a large class of parametric regression models such as GLMs,
and the PIs can work after model selection.

 Jan. 2013 1st draft of Robust Multivariate Analysis:
 http://lagrange.math.siu.edu/Olive/multbk.htm

 Here are some rejected Letters to the Editor. Erratum should have been published.

 This slightly revised letter was sent to the Journal of Computational and Graphical
Statistics about the latest FakeMCD estimator of Hubert, Rousseeuw and Verdonk (2012).
It pointed out that DetMCD is not the MCD estimator, that DetMCD has no theory,
and that it will be a massive undertaking to modify the theory for concentration estimators
in Olive and Hawkins (2010) to show whether DetMCD has any good properties.

 This paper shows that applying the Olive (2013b) nonparametric prediction region to
a bootstrap sample can result in a confidence region, and applying the prediction
region to Yhat_f + e_i, where the e_i are residual vectors, results in a nonparametric
prediction region for a future response vector Y_f for multivariate regression.

 This paper shows that the variable selection software originally meant
for multiple linear regression gives useful results for a much larger class of
models, including generalized linear models and single index models, if the Mallows' Cp
criterion is used. For models I with k predictors, the screen Cp(I) < 2k is much
more effective than the screen Cp(I) < k. Use response plots to show that the
final submodel is similar to the original full model.

rdist.pdf

 The following paper gives extremely important theoretical results.
It shows that software implementations for estimators of robust regression and
robust multivariate location and dispersion tend to be inconsistent with zero breakdown value.
The commonly used elemental basic resampling algorithm draws K elemental sets. Each
elemental fit is inconsistent, so the final estimator is inconsistent, regardless
of how the algorithm chooses the elemental fit.
The CM, GS, LMS, LQD, LTS, maximum depth, MCD, MVE, one step GM and GR, projection, S, tau,
t type, and many other robust estimators are of little applied interest because they are
impractical to compute. The "Robustifying Robust Estimators" paper shows how modify some
algorithms so that the resulting regression estimators are easily computed sqrt n consistent
high breakdown estimators and the resulting multivariate location and dispersion estimators
are sqrt n consistent with high outlier resistance.
