On the Markov Chain Central Limit Theorem - Statistics

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

Factor Analysis - University of Minnesota

Factor Analysis Model Model Form Factor Model with m Common Factors X = (X1;:::;Xp)0is a random vector with mean vector and covariance matrix . The Factor Analysis model assumes that X = + LF + where L = f‘jkgp m denotes the matrix offactor loadings jk is the loading of the j-th variable on the k-th common factor F = (F1;:::;Fm)0denotes the vector of latentfactor scores

Linear Mixed-Effects Regression - Statistics

Nesting typically introduces correlation into data at level-1 Students are level-1 and schools are level-2 Dependence/correlation between students from same school We need to account for this dependence when we model the data.

Robust Regression - University of Minnesota

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

The Analysis of Split-Plot Experiments

whole plots. The reason is that in this experimental design we have randomized the levels of A on the whole plots so that an experimental unit corresponding to A is a whole plot. Based on the additive split-plot model given by (7-2) a test for an effect of the whole plot factor A, that is the hypothesis H0: a(a 1) = = a(a k), is equivalent to ...

FRACTIONAL FACTORIAL DESIGNS Sometimes, there aren’t enough resources to run a Full Factorial Design. Instead, you can run a fraction of the total # of treatments. 2k-p kdesign = k factors, each with 2 levels, but run only 2-p treatments (as opposed to 2k) 24-1 design = 4 factors, but run only 23 = 8 treatments (instead of 16) 8/16 = 1/2 design known as a “½ replicate” or …
