Note: CHIINV is supplemented by the new identical function CHISQ.INV.RT, which is available in newer versions of Microsoft Excel (2010 or later).
Syntax:
CHIINV(Probability, DegreesFreedom)
Description:
This returns the inverse of the right-tailed probability of the chi-square distribution function (i.e., percentiles of this distribution).
Probability is the probability to be evaluated. The values must be within the range 0 to 1.
DegreesFreedom is the number of degrees of freedom. This value must be ≥ 1 and < 10^10. An integer is expected; if this is not the case, PlanMaker automatically truncates the decimal places.
Note:
The result of this function is calculated using an iteration method. If, after 100 iterations, PlanMaker does not find a result that deviates less than ±3x10^-7 from Probability, it displays the error value #N/A and cancels the approximation.
