According to Wikipedia the beta probability distribution has two shape parameters: $\alpha$ and $\beta$.
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.
After googling I found one of the return values must be 'location', since the third variable is 0 if I call
Does anyone know what the fourth variable is, and if the first two are $\alpha$ and $\beta$?
