BETA.DIST

Previous pageReturn to chapter overviewNext page

 

This function calculates the cumulative beta distribution function.

Syntax

BETA.DIST(x,alpha,beta,cumulative,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

cumulative

A logical value that determines the function form. The function returns the cumulative distribution function if this argument is true. It returns the probability density function, if the argument is false

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 except cumulative. Accepts TRUE or FALSE for cumulative. Returns numeric data.

Examples

BETA.DIST(A1,A3,B4,TRUE,1,3)

BETA.DIST(2,8,10,TRUE,1,3) gives the result 0.6854705810546875
