CHIINV(prob, degrees_freedom)

Return data type: number


Argument Description
prob A probability associated with the chi2 distribution. It must be a number between 0 and 1.
degrees_freedom An integer stating the number of degrees of freedom.

This function is related to the ChiDist function in the following way:
If prob = CHIDIST(value,df), then CHIINV(prob, df) = value


All arguments must be numeric, else NULL will be returned.
