BETA.DIST

Beta distribution[1].

Syntax:

BETA.DIST( x:Number, alpha:Number, beta:Number {, cumulative:Boolean {, lower_limit:Number {, upper_limit:Number} } } )

Returns the value of the cumulative distribution function (CDF) or the probability density function (PDF) for the beta distribution with given alpha and beta shape parameters at x.

cumulative selects CDF (TRUE, default) or PDF (FALSE).

If lower_limit is omitted the standard beta distribution lower limit of zero is used.

If upper_limit is omitted the standard beta distribution upper limit of one is used.

If given, these parameters are used to scale and shift the given x-value from [lower_limit..upper_limit] into the standardized beta distribution range [0..1].

This function was added in Fireworkz 2.00.
