Probability joint distribution
Webbinformation. 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, this is just our earlier notion of conditional probability re-expressed for discrete random variables, and from (1.7 ... WebbThe terms probability distribution function and probability function have also sometimes been used to denote the probability density ... often called joint probability density function. This density function is defined as a function of the n variables, such that, for any domain D in the n-dimensional space of the values of the ...
