CHIINV
Calculates the inverse of the CHIDIST function.
Syntax:
CHIINV(p; k)
- k is the (positive integer) degrees of freedom for the χ2-distribution.
- CHIINV(p; k) returns the value x, such that CHIDIST(x; k) is p.
Example:
CHIINV(0.5724; 3)
- returns approximately 2.
Issues:
- The draft international standard ODFF calls this function LEGACY.CHIINV, and defines a new CHISQINV function.
