Calculation of rho (
) value
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
and
, that is
where is used to define a overlap between two datasets and
is used to define effect variation.
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.
