CHIDIST(chisquared,df) returns the probability P associated with the test statistic chisquared and df degrees of freedom.

The argument chisquared can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the CHIDIST function applied to all elements.
