Manuscript Error:

Description

Error in solution for Exercise 1M21 or the exercise itself. One can find logical contradiction by looking at Y =10 and theta=0.2. Since the number of customers the made a purchase is Y=10, the number of customers n cannot be smaller than Y. However, when one examines the posterior distribution, all the mass is below n=10.

I believe that the error in the code is in the way that the observations are encoded ys = [0, np.ones(5), np.ones(10)] instead of [0, 5, 10]. It basically set k to 1 multiple times.
