A cumulative density function (CDF) gives the probability that XX is less than or equal to a value, say xx. A CDF is usually written as F(x)F(x) and can be described as: FX(x)=P(X≤x)FX(x)=P(X≤x) I like to subscript the X under the function name so that I know what...

Making the definition Q=∑i=1nαiχ21,c2i,Q=∑i=1nαiχ1,ci22, we say that QQ follows a generalized chi-square distribution. There is no particularly nice expression for the CDF for general μμ and ΣΣ. However, its characteristic function does have a nice form and can be ...
