WebDefinition \(\PageIndex{1}\) The probability mass function (pmf) (or frequency function) of a discrete random variable \(X\) assigns probabilities to the possible values of the random variable.More specifically, if \(x_1, x_2, \ldots\) denote the possible values of a random variable \(X\), then the probability mass function is denoted as \(p\) and we write WebFeb 6, 2012 · Here are three ways the negative binomial distribution can arise from violations of a Poisson distribution. ... a judicious choice of link function can constrain the predictions to map onto a desired range. The so-called canonical link functions for the normal, Poisson, binomial, and gamma distributions are respectively the identity, log, logit ...
