The BETA.DIST function is one of the statistical functions. It is used to return the beta distribution.
The BETA.DIST function syntax is:
BETA.DIST(x, alpha, beta, cumulative, [,[A] [,[B]])
x is the value between A and B at which the function should be calculated.
alpha is the first parameter of the distribution, a numeric value greater than 0.
beta is the second parameter of the distribution, a numeric value greater than 0.
cumulative is a logical value (TRUE or FALSE) that determines the function form. If it is TRUE, the function returns the cumulative distribution function. If it is FALSE, the function returns the probability density function.
A is the lower bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 0 is used.
B is the upper bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 1 is used.
The values can be entered manually or included into the cells you make reference to.
