Description: Returns the inverse of the Weibull cumulative distribution.
Syntax: weibullinv(Probability, Beta, Eta, Gamma)
Probability is the value at which the cumulative Weibull distribution is evaluated.
Beta is the shape parameter of the Weibull distribution.
Eta is the scale parameter of the Weibull distribution.
Gamma is the location parameter of the Weibull distribution.
Remarks:
Probability, Beta, Eta and Gamma must be numerical.
Probability must be > 0 and < 1.
Beta and Eta must be > 0.
All parameter values can include:
Numerical values
Standard operands (+, -, *, /)
Predefined mathematical functions (exp, log, sin, etc.)
