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 ...

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.

JMP Tutorial: Probability Histogram Suppose that the probability mass function (PMF) for the discrete random variable X is: f (x) = x/9 x=2,3,4 and zero otherwise.

Probability density functions (PDFs) have a wide range of uses across an array of application domains. Since computing the PDF of real-time data is typically expensive, various estimations have been ...

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 ...
