Simulating random walks in random streams
WebbThe random daily changes in stock prices cannot be predicted, but they can be modeled with a probability distribution. To model the time series we’ll start by visualizing the distribution of the change_d vector. In the example below the change_d vector is plotted using the empiricalDistribution function to create an 11 bin histogram of the data. . … Webb30 nov. 2024 · Using the random.choices function (as you do), this can be achieved using the weights parameter: from random import choices random_direction = choices (population= ['N', 'E', 'S', 'W'], weights= [1, 1, 2, 1], k=1) [0] You could make a single call of choices out of the for loop BTW, since this is a choice with replacement.
