gammaqInv and gammaqInva: Inverses of normalized gammaq function

Description

gammaqInv and gammaqInva: Inverses of normalized gammaq function

Usage

gammaqInv(a, q)

gammaqInva(x, q)

Arguments

a	The numeric 'a' parameter in the upper incomplete gamma
q	The numeric 'q' parameter in the upper incomplete gamma
x	The numeric 'x' parameter in the upper incomplete gamma

Details

With the equation:

q = gammaq(a, x)

The 'gammaqInv' function returns a value 'x' that satisfies the equation above

The 'gammaqInva' function returns a value 'a' that satisfies the equation above

NOTE: gammaqInva is slow

Value

inverse gammaq results
