WebThe marginal probability mass functions (marginal pmf's) of X and Y are respectively given by the following: pX(x) = ∑ j p(x, yj) (fix a value of X and sum over possible values of Y) pY(y) = ∑ i p(xi, y) (fix a value of Y and sum over possible values of X) Link to Video: Overview of Definitions 5.1.1 & 5.1.2 Example 5.1.1 WebA marginal likelihood is a likelihood function that has been integrated over the parameter space. In Bayesian statistics , it represents the probability of generating the observed sample from a prior and is therefore often referred to as model evidence or simply evidence .
