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 ... WebThe Poisson distribution is the limit of the binomial distribution for large N.

WebIt seems that Python is faster at comparison when done in a numpy array, and/or faster at doing list comprehensions when just checking truth rather than comparison. Edit: I was revisiting my code and I came across a possibly less memory intensive, bit faster, and super-concise way of doing this in one line: inds = np.arange( len(a) )[ a < 2 ] WebNotes#. Submatrix: Assignment to a submatrix can be done with lists of indices using the ix_ command. E.g., for 2D array a, one might do: ind=[1, 3]; a[np.ix_(ind, ind)] += 100.. HELP: There is no direct equivalent of MATLAB’s which command, but the commands help and numpy.source will usually list the filename where the function is located. Python also …
