What form does <strong>Bayes</strong>’ theorem assume<br />
when dealing with distributions<br />
Note:<br />
Σ j pr(H j )pr(D|H j ) = Sum of all probabilities of the data given all the<br />
hypotheses. It is very difficult to know all probabilities of data given all the<br />
hypotheses.<br />
Nevertheless, since this expression is the same denominator for each<br />
pr(H i ǀD):<br />
pr(H i ǀD)∝pr(H i )pr(DǀH i )<br />
and Σ j pr(H j )pr(DǀH j ) becomes a normalization constant to make the sum of<br />
all numerators = 1
