The Beta distribution is a family of continuous distributions on [0,1] with two parameters (commonly known as α\alphaα and β\betaβ, but also rrr and sss).

Beta distributions are commonly used in situations where we want to continually update a prior distribution given new information.

  • The beta (1,1) distribution is identical to the uniform distribution.
