The WEIBULL function returns the Weibull distribution. The Weibull distribution is one of the continuous probability distributions.
WEIBULL(non-neg-x-value, alpha, beta, form-type)
non-neg-x-value: A number value representing the x value at which you want to evaluate the function. non-neg-x-value must be greater than or equal to 0.
alpha: A number value representing the parameter describing the shape parameters of the distribution. alpha must be greater than 0.
beta: A number value representing the parameter describing the scale of the distribution. beta must be greater than 0.
form-type: A modal value that indicates which form of the exponential function to provide.
cumulative form (TRUE or 1): Return the value of the cumulative distribution form.
probability density form (FALSE or 0): Return the value of the probability density form.
Notes
The WEIBULL function has been implemented as a two-parameter Weibull distribution, which requires that non-neg-x-value must be greater than or equal to 0.
