In satabdisaha1288/scBT: What the Package Does (One Line, Title Case)

scBT

This package implements a new Bayesian test for detecting differential gene expression over multiple dose groups in single cell gene expression studies.

DGE testing

scBT is an R package for differential gene expression (DGE) analysis in multiple group study designs for single-cell RNA sequencing data. scBT contains a new Bayesian test of the same name designed along with 9 other benchmarking algorithms frequently used for the DGE analysis in multiple group experimental designs. The tests present in scBT are:

• Seurat Bimod ( Two sample test of mean for zero inflated continuous data)
• Wilcoxon Rank Sum Test (Non-parametric two sample test for mean)
• ANOVA ( Parametric K-sample test of mean for samples from a normal distribution)
• KW (Non-parametric K-sample test of mean)
• limma-trend
• LRT-multiple(k-sample test of mean for zero inflated continuous data)
• LRT-Linear( Regression model based test of DGE for zero inflated continuous data)
• MAST (Regression model based test of DGE for zero inflated continuous data with Bayesian estimation)

Installation

Install dependencies

# brglm
install.packages('brglm')
