varBP: Get variance of a beta-Poisson model

In nghiavtr/BPSC: Beta-Poisson Model for Single-Cell RNA-seq Data Analyses

Description

Get variance of a beta-Poisson model

Usage

varBP(alp, bet, lam1 = 1, lam2 = 1, prob0 = 0)

Arguments

alp	A non-negative value, the parameter of Beta function (alpha)
bet	A non-negative value, the parameter of Beta function (beta)
lam1	A non-negative value, the parameter for scaling
lam2	A non-negative value, the parameter for smoothing, used for BP4 or BP5
prob0	A non-negative value in [0;1), the parameter for the portion of fixed density of zero in the distribution, used for BP5

Value

The variance of a beta-Poisson model

Examples

varBP(alp=0.6,bet=1.5,lam1=20,lam2=0.05)
