BETADIST Function in Excel calculates the cumulative beta probability density function for a supplied set of parameters.
Syntax of BETADIST Function in Excel:
BETADIST(x, alpha, beta, [A], [B])
- X -The value at which the function is to be calculated (must be between [A] and [B]).
- alpha -A parameter of the distribution (must be > 0).
- beta -A parameter of the distribution (must be > 0).
- [A] -An optional argument with default value 0, which gives the lower bound of the interval of x.
- [B] -An optional argument with default value 1, which gives the upper bound of the interval of x.
Example of BETADIST Function in Excel
Formula
- Beta Distribution function BETADIST is supplied values from 0 to 1 on interval of 0.1 along with alpha value as 6 and beta value as 8.
So the result will be cumulative beta probability density function ranging from 0 to 1 as shown below.
Result
Cumulative Beta Distribution of x ranging from 0 to 1 with alpha =6 and beta=8 is plotted below
