CHIINV

Description: Returns the inverse of the one-tailed probability of the chi-squared distribution. If Probability = CHIDIST(x,...), then CHIINV(Probability,...) = x.

Syntax: CHIINV(Probability, Degr_Freedom)

• Probability is a probability associated with the chi-squared distribution.

• Degr_Freedom is the number of degrees of freedom.

Remarks:

• Both arguments must be numerical.

• Probability must be > 0 and < 1.

• Degr_Freedom must be an integer.

• Degr_Freedom must be >= 1 and <= 10^10.

Example:

• CHIINV(0.050001,10) = 18.3069735
