- Weibull[ <Shape>, <Scale>, x ]
- Creates probability density function (pdf) of Weibull distribution with parameters shape k and scale λ
- Weibull[ <Shape>, <Scale>, x, <Boolean Cumulative> ]
- If Cumulative is true, creates cumulative distribution function of Weibull distribution, otherwise creates pdf of Weibull distribution.
- Weibull[ <Shape>, <Scale>, <Variable Value> ]
- Calculates the value of cumulative distribution function of Weibull distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with Weibull distribution given by parameters shape k and scale 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).
- Examples:
Weibull[ 0.5, 1, 0]
yields 0.Weibull[ 0.5, 1, 1]
yields 1 - \frac{1} { e } .
