Function name:
CHISQINV

Category:
Statistical Analysis

Summary:
Returns the inverse of the cumulative distribution function for the one-tailed chi-square distribution.

Syntax:
CHISQINV(Probability; DegreesFreedom)

Returns:
Returns a non-negative real number which is the inverse cumulative distribution function for the one-tailed chi-square distribution. If p = CHISQDIST(x;n), then CHISQINV(p,n) = x.

Arguments:
Probability is a real number from 0 to 1 or a reference to the cell containing that number which is the probability value for which the inverse of the chi-square distribution is to be calculated.

DegreesFreedom is a positive integer or a reference to a cell containing that number which is the degrees of freedom for the chi-square function.


 * If Probability is greater than 1 or less than 0, then the function returns an error value.
 * If DegreesFreedom is less than 1, the function returns an error value.
 * If DegreesFreedom is a non-integer numeric value, then the function truncates it to an integer.
