WebbIn this section we’ll replace the Bayes table with a more compact representation, a probability mass function, or PMF. A PMF is a set of possible outcomes and their corresponding probabilities. There are many ways to represent a PMF; in this notebook I’ll use a Pandas Series. WebbThe joint probability mass function (joint pmf) of X and Y is the function p(x i;y j) giving the probability of the joint outcome X = x i; Y = y j. We organize this in a joint probability …

WebbIf XX and YY are independent, then we can multiply the probabilities, by Theorem 7.1 : P(X = x) ⋅ P(Y = y). But P(X = x)P (X = x) is just the marginal distribution of XX and P(Y = y)P (Y =y) the marginal distribution of YY. So this is equal to: fX(x) ⋅ fY(y) Let’s calculate another marginal distribution—this time from the formula ...
