Modeling Costs with Generalized Gamma Regression.
Downloadable! glgamma2 fits a maximum-likelihood generalized 2-parameter log-gamma regression model of depvar on indepvars, where depvar is a non-negative count variable. The program may be used to model under-dispersed Poisson count data. Under-dispersion is indicated if the scale parameter, phi, is greater than 1; values under 1 indicate over-dispersion.
Gauss Moutinho Cordeiro (born April 17, 1952) is a Brazilian engineer, mathematician and statistician who has made significant contributions to the theory of statistical inference, mainly through asymptotic theory and applied probability. Education. He received his PhD in Statistics in 1982 at Imperial College London supervised by David Roxbee Cox. Research. Currently, Cordeiro is a Class A.
Most results in nonparametric regression theory are developed only for the case of additive noise. In such a setting many smoothing techniques including wavelet thresholding methods have been developed and shown to be highly adaptive. In this paper we consider nonparametric regression in exponential families with the main focus on the natural exponential families with a quadratic variance.

Quantile regression offers an extension to regression analysis where a modified version of the least squares method allows the fitting of quantiles at every percentile of the data rather than the mean only. Using the well-known three-parameter generalised gamma distribution to model variation in data, we present a parametric quantile regression study for positive univariate reference charts.
