The Frisch–Waugh–Lovell theorem for the lasso and the ridge regression

The Frisch–Waugh–Lovell (FWL) (partitioned regression) theorem is essential in regression analysis. This is partly because it is quite useful to derive theoretical results. The lasso regression and the ridge regression, both of which are penalized least-squares regressions, have become popular statistical techniques. This article describes that the FWL theorem remains valid for these penalized least-squares regressions. More precisely, we demonstrate that the covariates corresponding to unpenalized regression parameters in these penalized least-squares regression can be projected out. Some other results related to the FWL theorem in such penalized least-squares regressions are also presented.     

Evaluation of Research Ethics Committees: Criteria for the Ethical Quality of the Review Process

Repeatedly, adequacy, performance and quality of Ethics Committees that oversee medical research trials are being discussed. Although they play a crucial role in reviewing medical research and protecting human subjects, it is far from clear to what degree they fulfill the task they have been assigned to. This eventuates in the call for an evaluation of their activity and, in some places, led to the establishment of accreditation schemes. At the same time, IRBs have become subject of detailed legislation in the process of the ongoing global juridification of medical research. Unsurprisingly, there is a tendency to understand the evaluation of RECs as a question of controlling their legal compliance. This paper discusses the need for a quality evaluation of IRBs from an ethical point of view and, by systematically reviewing the major ethical guidelines for IRBs, proposes a system of criteria that should orientate any evaluation of IRBs.
