The main objective of this work is to connect the theoretical work of Schmeidler (1989) on decision making with Choquet expected utility to recent developments in risk assessment and show that portfolio optimization for Choquet decision makers with linear utility can be conducted by solving a special class of quantile regression problems. Software for the project is available as an R package and is available as a R source package as qrisk_0.05.tar.gz, and as an Windows binary package as qrisk_0.05.zip. For further details on installation and R more generally see CRAN. CRAN. As the version number of the qrisk package indicates this is an early alpha-stage and we would greatly value any comments and suggestions that users may have about it.
