WebA cumulative distribution function (CDF) describes the probabilities of a random variable having values less than or equal to x. It is a cumulative function because it sums the total likelihood up to that point. Its output always ranges between 0 and 1. CDFs have the following definition: CDF (x) = P (X ≤ x) Web• Distribution that maximizes Λis the maximum likelihood distribution for the data and provides the best fit for the distributions of form p • Maximum likelihood also provides measure of the goodness of fit for distributions of form p • Moving away from the maximum, Λ~Normal, so the confidence contours scale as χ 2 distribution with # of
