Abstract
The characteristic function of three-parameter Weibull distribution is also derived independently and the moment generating function (MGF) is deduced from it. It generates all the moments of the distribution and satisfies the tests to verify a function to be a characteristic function. Expressions for mean, variance, skewness and kurtosis are also obtained from MGF.
