WebMar 13, 2012 · The exponentiated gamma (EG) distribution and Fisher information matrices for complete, Type I, and Type II censored observations are obtained. Asymptotic variances of the different estimators are derived. Also, we consider different estimators and compare their performance through Monte Carlo simulations.

Webdistribution acts like a Gaussian distribution as a function of the angular variable x, with mean µand inverse variance κ. This example can be generalized to higher dimensions, where the sufficient statistics are cosines of general spherical coordinates. The resulting exponential family distribution is known as the Fisher-von Mises distribution. Webis the logarithmic integral function. [2] In probability theory and statistics, the generalized extreme value ( GEV) distribution [3] is a family of continuous probability distributions developed within extreme value theory to combine the Gumbel, Fréchet and Weibull families also known as type I, II and III extreme value distributions.
