Bartlett and Bartlett-type corrections in heteroscedastic symmetric nonlinear regression models
Abstract This paper provides general expressions for Bartlett and Bartlett-type correction factors for the likelihood ratio and gradient statistics to test the dispersion parameter vector in heteroscedastic symmetric nonlinear models. This class of regression models is potentially useful to model da...
