Remarks

Important

This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. This function is still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider using the new functions from now on, because they more accurately describe their functionality. For more information about the new function, see the Beta_Dist(Double, Double, Double, Boolean, Object, Object) method.

The beta distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.

  • If any argument is nonnumeric, BetaDist returns the #VALUE! error value.

  • If alpha ≤ 0 or beta ≤ 0, BetaDist generates an error value.

  • If x < A, x > B, or A = B, BetaDist generates an error value.

  • If you omit values for A and B, BetaDist uses the standard cumulative beta distribution, so that A = 0 and B = 1.
