diffMeanVar (version 0.0.6)

Detecting Gene Probes with Different Means or Variances Between Two Groups

Description

A collection of functions to detect gene probes with different means or variances between two groups in (epi)-genomic data analysis, including classical F test and Levene's test for equal variance, likelihood ratio test for equal mean and equal variance, the wrappers for functions in R Bioconductor package 'missMethyl' (Phipson and Oshlack (2014) ), the implementation of the methods proposed by Ahn and Wang (2013) , and the improved Ahn and Wang's methods that we proposed recently (Qiu and Li et al. (2017) ).
