rhov: Calculation of rho (rho) value

In tatest: Two-Group Ta-Test

Description

The rho is used to define a gap and variation between two datasets, similar to fc(fold change).

Usage

rhov(XA, XB)

Arguments

XA	a numeric vector in condition A.
XB	a numeric vector in condition B.

Details

The rho is defined as square root of products of

ψ

and

ζ

, that is

ρ=√{ψζ}

where ψ is used to define a overlap between two datasets and ζ is used to define effect variation. ρ > 1 indicates that there is gap between two datasets and noise is smaller than treatment effect, otherwise, there is overall lap and big noise in two datasets.

Value

return a numeric value
