This function calculates the cumulative beta distribution function.
BETA.DIST(x,alpha,beta,cumulative,lower,upper)
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 |
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.
Accepts numeric data for all arguments except cumulative. Accepts TRUE or FALSE for cumulative. Returns numeric data.
BETA.DIST(A1,A3,B4,TRUE,1,3)
BETA.DIST(2,8,10,TRUE,1,3) gives the result 0.6854705810546875
