Summary: | To provide an integrated software environment for model fitting and variable selection in regression models with a bounded outcome variable.
The proposed modelling framework is implemented in the add-on package betaboost of the statistical software environment R.
The betaboost methodology is based on beta-regression, which is a state-of-the-art method for modelling bounded outcome variables. By combining traditional model fitting techniques with recent advances in statistical learning and distributional regression, betaboost allows users to carry out data-driven variable and/or confounder selection in potentially high-dimensional epidemiological data. The software package implements a flexible routine to incorporate linear and non-linear predictor effects in both the mean and the precision parameter (relating inversely to the variance) of a beta-regression model.
