CHISQINV

Calculates the inverse of the CHISQDIST function.

Syntax

CHISQINV(p; k)

k is the degrees of freedom for the χ2-distribution.
Constraint: k must be a positive integer
p is the given probability
Constraint: 0 ≤ p < 1

Semantic

CHISQINV(p; k) returns the value x, such that CHISQDIST(x; k;TRUE()) = p.

Example

CHISQINV(0.5; 9)

returns approximately 8.342832692.

Remarks

If you need CHISQINV(p;k) for a non-integer parameter k, then use GAMMAINV(p;k/2;2) instead.
