BETA.DIST function
x
The value at which to evaluate the function.
alpha
A parameter to the distribution.
beta
A parameter to the distribution.
isCumulative
TRUE, which calculates the cumulative distribution function. The value FALSE, which would have calculated the probability density function, is not supported.
a
A lower bound for the x parameter. If omitted, the lower
bound is assumed to be 0.
b
An upper bound for the x parameter. If omitted, the upper
bound is assumed to be 1.
Returns
A value for a beta distribution.
Returns the cumulative distribution function or the probability density
function of a beta distribution. The beta distribution is a family of
continuous probability distributions, where the alpha and
beta parameters control the shape of the distribution. The
x parameter is the number at which the beta distribution is
evaluated.
