What is a Probability Mass Function (PMF)? A probability mass function (PMF), sometimes referred to as a frequency function, is a function that associates probabilities with discrete random variables.

A probability mass function (PMF), sometimes referred to as a frequency function, is a function that associates probabilities with discrete random variables. You already learned about this in the ...

We develop an estimation procedure for a discrete probability mass function (pmf) with unknown support. We derive its maximum likelihood estimator under the mild and natural shape-constraint of ...
