Inverse Chi-Sq
Description
Inverse Chi-Sq
Usage
chi2inv(x, n)
Arguments
x
probability that Chi^2 random variable is less than or equal to x (scalar).
n
degrees of freedom(scalar)
Details
Computes the inverse Chi^2 distribution corresponding to a given
probability that a Chi^2 random variable with the given degrees
of freedom is less than or equal to x. Uses chi2cdf.m.
Value
corresponding value of x for given probability.
