In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval 1 parametrized by two positive shape parameters, denoted by α and β, that appear as exponents of the random variable and control the shape of the distribution.
The probability density function of the beta distribution, for 0 ≤ x ≤ 1, and shape parameters α > 0 and β > 0, is a power function of the variable x and of its reflection ( 1-x ) as follows:

# Finding a solution for unknown parameters β that will, for example, minimize the distance between the measured and predicted values of the dependent variable Y ( also known as method of least squares ).
# Under certain statistical assumptions, the regression analysis uses the surplus of information to provide statistical information about the unknown parameters β and predicted values of the dependent variable Y.
