Description

prob

Probability of the distribution

lower

[Optional] Lower bound of the interval for x; 0 if omitted

upper

[Optional] Upper bound of the interval for x; 1 if omitted

If you omit values for upper and lower, the calculation uses the standard cumulative beta distribution, so that lower is zero and upper is one.

Data Types

Accepts numeric data for all arguments. Returns numeric data.

Examples

BETAINV(0.75,B3,C3,2,4)

BETAINV(0.75,R3C2,R3C3,2,4)
