Chi-Sq CDF
Computes the Chi^2 CDF, using a transformation to N(0,1) on page 333 of Thistead, Elements of Statistical Computing.
chi2cdf(x, n)
x |
end value of chi^2 pdf to integrate to. (scalar) |
n |
degrees of freedom (scalar) |
Note that x and m must be scalars.
p |
probability that Chi^2 random variable is less than or equal to x (scalar). |
