%% Compute and Plot Hypergeometric Distribution CDF % This example shows how to compute and plot the cdf of a hypergeometric % distribution. % Copyright 2015 The MathWorks, Inc. %% % Compute the cdf of a hypergeometric distribution that draws 20 samples % from a group of 1000 items, when the group contains 50 items of the % desired type. x = 0:10; y = hygecdf(x,1000,50,20); %% % Plot the cdf. stairs(x,y) %% % The x-axis of the plot shows the number of items drawn that are of the % desired type. The y-axis shows the corresponding cdf values.
