Histogram of the residuals
WebbThis can also be seen on the histogram of the residuals. The histogram suggests that the residuals may not be normal — the right tail seems a little too long, even when we … WebbA normed histogram is defined such that the sum of products of width and height of each column is equal to the total count. That's why you are not getting your max equal to one. However, if you still want to force it to be 1, you could use numpy and matplotlib.pyplot.bar in the following way
