"WebThis method of estimation of distribution parameters was introduced by Karl Pearson in 1894. The Power Density method is also a method of moments. It ensures that the energy content of the fitted Weibull distribution equals the energy content of the observed histogram. Wind energy is the kinetic energy of an air mass.
