Weibull Command

Weibull[ <Shape k>, <Scale λ>, x]

Creates probability density function (pdf) of Weibull distribution with parameters k, λ.

Weibull[ <Shape k>, <Scale λ>, x, <Boolean Cumulative> ]

If Cumulative is true, creates cumulative distribution function of Weibull distribution, otherwise creates pdf of Weibull distribution.

Weibull[ <Shape k>, <Scale λ>, <Variable Value v> ]

Calculates the value of cumulative distribution function of Weibull distribution at v, i.e. the probability P(X≤v) where X is a random variable with Weibull distribution given by parameters k, λ.

Note: Returns the probability for a given x-coordinate's value (or area under the Weibull distribution curve to the left of the given x-coordinate).
