On the Markov Chain Central Limit Theorem - Statistics

users.stat.umn.edu

On the Markov Chain Central Limit Theorem Galin L. Jones School of Statistics University of Minnesota Minneapolis, MN, USA galin@stat.umn.edu Abstract The goal of this paper is to describe conditions which guarantee a central limit theorem for functionals of general state space Markov chains. This is done with a view towards Markov

All split plots in the same whole plot get the same level of the whole plot treatment factor. All levels of the split plot treatment factor occur in each whole plot. The restricted randomization is equivalent to the two randomizations of the unit structure approach.

Robust Regression - University of Minnesota

users.stat.umn.edu

Robust Regression John Fox & Sanford Weisberg October 8, 2013 All estimation methods rely on assumptions for their validity. We say that an estimator or statistical procedure is robust if it provides useful information even if some of the assumptions used to justify the estimation method are not applicable. Most of this appendix concerns robust
