Web21 Oct 2013 · scipy.stats.betaprime. ¶. scipy.stats.betaprime = [source] ¶. A beta prime continuous random variable. Continuous random variables are defined from a standard form and may require some shape parameters to complete its specification. Web6 Mar 2024 · To model this belief, let’s pick a beta distribution with α = 4 and β = 10. We can plot this distribution via: import matplotlib.pyplot as plt from scipy.stats import beta x = np.linspace (0, 1, 100) plt.plot (x, beta.pdf (x, 4, 10)) plt.show () Resulting in the following plot: Image generated by author Using this prior, we obtain:

WebAccording to Wikipedia the beta probability distribution has two shape parameters: α and β. When I call scipy.stats.beta.fit (x) in Python, where x is a bunch of numbers in the range [ 0, 1], 4 values are returned. This strikes me as odd. Web21 Nov 2024 · The scipy.stats.beta.fit () method (red line) is uniform always, no matter what parameters I use to generate the random numbers. x=0 in the beta distribution. And if given a real world problem, isn't it the 1st step to normalize the sample observations to make it in between [0,1] ? In that case, how should I fit the curve?
