Conditional probability distribution example
Webinformation about how the knowledge of one random variable’s outcome may affect the other: conditional information. We formalize this as a conditional probability function, defined by p(yjx) = P(Y = yjX = x); (3:5) which we read as “the probability that Y = y given that X = x.” Since “Y = y” and “X = x” are events, WebInverse probability and Bayes’ rule A common situation: There is a \parameter" whose value we don’t know, but we believe that a random variable Y has a distribution, conditional on , with density p(y j ). Before we observe Y our uncertainty about is characterized by the pdf ˇ( ). The rule for forming conditional densities from joint can be ...
