Where:

This function is used to study percentage variations for an item across population samples (for example, how much of a day people spend watching television).

Syntax

BetaDistribution < Lower Bound, Upper Bound > (x, alpha, beta)

Where:

x is the value between Lower Bound (a) and Upper Bound (b) at which the function is evaluated.

alpha and beta are distribution parameters.

  • alpha =
  • beta =

Lower Bound is an optional lower bound of the interval of x.

Upper Bound is an optional upper bound of the interval of x.

Usage Notes

The following conditions are invalid:

  • x, alpha, or beta is nonnumeric.
  • alpha £ 0 or beta £ 0.
  • x < Lower Bound or x > Upper Bound.
  • Lower Bound = Upper Bound.
