In eq.28, n, , are parameters, and B( , ) is beta function. Probability distribution function is given by eq.29. (29) (30) Eq.30 is probability density function of beta distribution. The expectation and variance of random variable, X which is followed by beta binomial distribution is given by eq.31 and 32 respectively. (31) (32) Model

Probability Distribution of a Discrete r.v. The probability distribution of a discrete r.v. x, denoted as p(x), describes the probabilities that the r.v. x takes all possible values. The function p(x) is called the probability mass function. Ex. x = # of head in tossing a fair coin. Then the probability distribution of x is . P(0) = P[x=0] = P ...
