If you want to plot a distribution, and you know it, define it as a function, and plot it as so: import numpy as np from matplotlib import pyplot as plt def my_dist (x): return np.exp (-x ** 2) x = np.arange (-100, 100) p = my_dist (x) plt.plot (x, p) plt.show () If you don't have the exact distribution as an analytical function ... WebThe integral of a pdf must be equal to one: ∫ − ∞ ∞ f ( x) d x = 1. In this case, since the function g ( x) = sin ( π x / 10) is defined in 0 ≤ x ≤ 10 and g ( x) ≥ 0 in this interval: ∫ − ∞ ∞ g ( x) d x = ∫ 0 10 sin ( π x / 10) = 20 π. Then, we scale function g ( x) with the inverse of this value and the fdp would be ...
