WebA probability mass function (PMF) — also called a frequency function — gives you probabilities for discrete random variables. “Random variables” are variables from experiments like dice rolls, choosing a number out of a hat, or getting a high score on a test. The “discrete” part means that there’s a set number of outcomes. WebSep 24, 2024 · In the bayesian case, it is also the formula for the PMF that is used for the likelihood, but here the PMF is considered an already conditional PMF, because $\theta$ is regarded a random variable. So I guess my big mistake is to somehow expect the formula for the PMF and the conditional PMF to look different.
