Probability Density Function (PDF) vs Cumulative Distribution Function (CDF) The CDF is the probability that random variable values less than or equal to x whereas the PDF is a probability that a random variable, say X, will take a value exactly equal to x. This page provides ...
P.S.: if you try to get rid of the loops in your original code and have simply x = np.arange(x_lower, x_upper, (x_upper - x_lower) / (num_iter - 1)), cdf is again faster. The reason can be that cdf is computed with polynomials approximations. But I did not find informati...
