Conditional probability algorithm

WebApplications of conditional probability. An application of the law of total probability to a problem originally posed by Christiaan Huygens is to find the probability of “ gambler’s ruin.” Suppose two players, often called Peter and Paul, initially have x and m − x dollars, respectively. A ball, which is red with probability p and black with probability q = 1 − p, … WebThe algorithm. Starting from an initial guess , the -th iteration of the EM algorithm consists of the following steps: use the parameter value found in the previous iteration to compute the conditional probabilities for each ; use the conditional probabilities derived in step 1 to compute the expected value of the complete log-likelihood:
