WebIf P is a distribution for V with probability function p(x), we say that P is Markov to G, or that G represents P, if p(x)= Yd j=1 p(x j ⇡ x j) (18.2) where ⇡ x j is the set of parent nodes of X j. The set of distributions represented by G is denoted by M(G). 18.3 Example. Figure 18.5 shows a DAG with four variables. The probability function WebFor normalization purposes. The integral of the rest of the function is square root of 2xpi. So it must be normalized (integral of negative to positive infinity must be equal to 1 in order to define a probability density distribution). Actually, the normal distribution is based on the function exp (-x²/2). If you try to graph that, you'll see ...
