Documentation/How Tos/Calc: CHIINV function

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.
