pratio: Calculation of psi (psi )

In NBBttest: Negative Binomial Beta t-Test

Calculation of psi (ψ )

Description

ψ is also called polar ratio. It is used to measure overlap of two subdatasets. If ψ>1, these two subdatasets have a gap, while ψ <1 indicates that two subdatasets overlap.

Usage

pratio(xx, na, nb)

Arguments

xx	count data of RNA reads generated by next generation sequencing.
na	number of replicate libraries in condition A.
nb	number of replicate libraries in condition B.

Details

Psi (ψ ) is defined as

ψ = max≤ft(\frac{min(X_A)}{max(X_B)},\frac{min(X_B)} {max(X_A)}\right)

Value
