S t is also called a random walk. The distribution of S T is given by (s 0 known at time 0) S T = s 0 +2Y −T, with Y ∼ Bin(T,p) Therefore the price P is (assuming s 0 = 0 without loss of generality)

WebApr 24, 2024 · The Poisson distribution has important connections to the binomial distribution. First we consider a conditional distribution based on the number of arrivals of a Poisson process in a given interval, as we did in the last subsection. Suppose that (Nt: t ∈ [0, ∞)) is a Poisson counting process with rate r ∈ (0, ∞). Web3.2.5 Negative Binomial Distribution In a sequence of independent Bernoulli(p) trials, let the random variable X denote the trialat which the rth success occurs, where r is a fixed integer. Then P(X = x r,p) = µ x−1 r −1 pr(1−p)x−r, x = r,r +1,..., (1) and we say that X has a negative binomial(r,p) distribution. The negative binomial distribution is sometimes … inch to square meter
