Calculates values for a Weibull distribution.

WEIBULL(x; k; λ; mode)

The Weibull distribution is a continuous probability distribution, with parameters k > 0 (shape) and λ > 0 (scale).

If mode is 0, WEIBULL calculates the probability density function of the Weibull distribution:

If mode is 1, WEIBULL calculates the cumulative distribution function of the Weibull distribution:

WEIBULL(2.5; 3; 4; 1)

returns approximately 0.2166, the value of the probability density function with k = 3 and λ = 4 at x = 2.5.

WEIBULL(2.5; 3; 4; 0)

returns approximately 0.2295, the value of the cumulative distribution function with k = 3 and λ = 4 at x = 2.5.
