ckn.m function y = ckn(P,k) determines the probability of the occurrence of k or more of the n independent events whose probabilities are in row or column vector P ( k may be a row or column vector)

function y = ckn(P,k) % CKN y = ckn(P,k) Probability of k or more successes% Version of 5/15/95 % Probabilities of k or more of n independent events% Uses the m-functions mintable, minprob, csort n = length(P);m = length(k); T = sum(mintable(n)); % The number of successes in each mintermpm = minprob(P); % The probability of each minterm [t,p]= csort(T,pm); % Sorts and consolidates success numbers % and adds corresponding probabilitiesfor i = 1:m % Sums probabilities for each k value y(i) = sum(p(k(i)+1:n+1));end

Conditional probability and conditional idependence

bayes.m produces a Bayesian reversal of conditional probabilities. The input consists of P ( E | A i ) and P ( A i ) for a disjoint class { A i : 1 i n } whose union contains E . The procedure calculates P ( A i | E ) and P ( A i | E c ) for 1 i n .
