This function calculates the cumulative beta distribution function.

Syntax

BETADIST(x,alpha,beta,lower,upper)

Arguments

This function has these arguments:

Argument	Description
x	Value at which to evaluate the function, between the values of lower and upper
alpha	Alpha parameter of the distribution
beta	Beta parameter of the distribution
lower	[Optional] Lower bound of the interval for x; 0 if omitted
upper	[Optional] Upper bound of the interval for x; 1 if omitted

Remarks

If you omit values for upper and lower, the calculation uses the standard cumulative beta distribution, so that lower is zero and upper is one.

Data Types

Accepts numeric data for all arguments. Returns numeric data.

Examples

BETADIST(3,B3,C3,2,4)

BETADIST(3,R3C2,R3C3,2,4)

BETADIST(3,6,9,2,4) gives the result 0.7880249023
