WebAug 23, 2024 · numpy.random.poisson(lam=1.0, size=None) ¶. Draw samples from a Poisson distribution. The Poisson distribution is the limit of the binomial distribution for large N. Parameters: lam : float or array_like of floats. Expectation of interval, should be >= 0. A sequence of expectation intervals must be broadcastable over the requested size. WebIn general, the stock price process is given by. S ( t) = S ( 0) e ( r − q − ω) t + X ( t), where ω is the drift term that makes the discounted stock price process a martingale and where X ( t) = σ W ( t) + ∑ i = 1 N ( t) Y i is a jump-diffusion process. The process N ( t) is a Poisson process with intensity λ and the jump sizes Y i ...
