Description Usage Arguments Details Value Author(s) References See Also Examples

Psi is also called polar ratio.

ψ = max(\frac{min(X_A)}{max(X_B)+1},\frac{min(X_B)}{max(X_A)+1})

1	pratio(xx, na, nb)

`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.

Psi is defined as

ψ = max(\frac{min(X_A)}{max(X_B)+1},\frac{min(X_B)}{max(X_A)+1})

It is used to measure overlap of two subdatasets. ψ>1, these two subdatasets have a gap, not overlap. ψ<1 indicates that two subdatasets overlap.
