Permutation Tests in R!

“ There are many situations were parametric linear model significance tests are not optimal (including when data is notably non-normal, there are outliers, and when sample sizes are too small to trust asymptotic results). In these cases, permuation tests may be viable alternatives.” lmPerm package provides permutation tests for linear models in R. It can be used for ANOVA, ANCOVA, polynomial regression, and multiple regression.

Bayesian Estimation of Negative Binomial Regression Using SAS

What is Negative Binomial Regression?

If you want to model count variables, negative binomial regression is a good choice. In this regression, the count variable, outcome, is regressed to your covariate of interest. As an example suppose that an insurance company is interested in analyzing the behavior of its insurees on visiting hospitals based on their characteristics to design the most appropriate and cost efficient plans for its customers.
