WebI have two tables One contains the cumulative distribution function (cdf) of a discrete random variable X (provided as F(k)). I need to finish the table by calculating the probability distribution function (pdf) of X (Pr(X=k)). The other table has the opposite, with the psf provided as Pr(X=k) and asking for the cdf as F(k) WebR: A Language and Environment for Statistical Computing.
