Original Issue Discount ( OID) is a type of interest that is not payable as it accrues. OID is normally created when a debt, usually a bond, is issued at a discount.

Methods for random number generation where the marginal distribution is a binomial distribution are well-established. [43] [44] One way to generate random variates samples from a binomial distribution is to use an inversion algorithm. To do so, one must calculate the probability that Pr(X = k) for all values k from 0 through n. (These ...
