BETADIST

Description: Returns the cumulative beta probability distribution function.

Syntax: BETADIST(Number, Alpha, Beta)

• Number is the value at which to evaluate the function.

• Alpha is a parameter of the distribution.

• Beta is a parameter of the distribution.

Remarks:

• All arguments must be numerical.

• Alpha and Beta must be > 0.

• When used in an event analysis flowchart, the parameters must evaluate to numerical values. They can include:

• Numerical values

• Standard operands (+, -, *, /)

• Predefined mathematical functions (exp, log, sin, etc.)

• Event analysis internal functions

• Event analysis resources

• References to any ReliaSoft Workbooks

Example:

• BETADIST(0.3, 8, 10) = 0.1046400948
