In beyondpie/mssc: Multiple-sample differential analysis for single-cell RNA sequencing data

Description

NOTE: From observation, mean can be estimate well, but if it's below 1, then r tends to be estimated too small.

Usage

initNBParam(y, s, default_r)

Arguments

y	numeric vector, should be not all zeros.
s	numeric vector, normalizing constant, should no zeros.
default_r	numeric scalar, when variance larger than m, it will be used.

Value

list of two-named scalar, mu and r
