Improved estimators in beta prime regression models [PDF]
Communications in Statistics - Simulation and Computation, 2021 In this paper, we consider the beta prime regression model recently proposed by \cite{bour18}, which is tailored to situations where the response is continuous and restricted to the positive real line with skewed and long tails and the regression structure involves regressors and unknown parameters.

Journal of Statistical Software, 2010 The class of beta regression models is commonly used by practitioners to model variables that assume values in the standard unit interval (0, 1). It is based on the assumption that the dependent variable is beta-distributed and that its mean is related to a set of regressors through a linear predictor with unknown coefficients and a link function.

A Sarmanov Distribution with Beta Marginals: An Application to Motor Insurance Pricing
Mathematics, 2020 Background: The Beta distribution is useful for fitting variables that measure a probability or a relative frequency. Methods: We propose a Sarmanov distribution with Beta marginals specified as generalised linear models.

Modelling Spatially Sampled Proportion Processes
Revstat Statistical Journal, 2018 Many ecological processes are measured as proportions and are spatially sampled. In all these cases the standard procedure has long been the transformation of proportional data with the arcsine square root or logit transformation, without considering ...
