Status Update: MSA Framework by TransCelerate

in news

May 20, 2021

TransCelerate has published “Modernization of statistical analytics (MSA) Framework”. With goals similar to the R Validation Hub, the TransCelerate MSA framework seeks to demonstrate software reliability by establishing principles of accuracy, traceability, and reproducibility for a modern analytical software environment. The MSA framework is centered around risk-assessment and mitigation practices to demonstrate reliability of software. This framework suggests assessing the accuracy of a software library via a confidence measure built on risk metrics such as published source code, issue management, usage, maturity, etc.

Status Update: A summary of 2020

in news

January 13, 2021

2020 was a busy year for the R Validation Hub. We released our white paper describing our current thinking on a risk based approach to using R for regulatory work. We started to support the implementation of the white paper with tools such as riskmetric and our risk assessment application. And we started a new sub-team with the aim of producing a follow-up white paper on testing. Throughout, we have continued to share and gain feedback on our proposed approach, presenting at User!

rOpenSci, Statistical Software, and the R Validation Hub

in news

September 21, 2020

Background rOpenSci is an organization devoted to “transforming science through data, software and reproducibility.” One of rOpenSci’s focal activities is peer review of R packages, historically focusing on packages that cover the data management lifecycle. This has historically excluded software implementing statistical methods, for which standards and review require addressing a different set of challenges. This year, we have begun tackling these so as to expand our peer review system to explicitly encompass statistical software, under project funded by the Alfred P.

Risk Assessment Application

in news

August 5, 2020

Background Towards the end of 2019, the R Validation Hub received an additional grant from the R Consortium to progress the next phase of our road map and produce a risk assessment app to complement the riskmetric package. In early 2020, Fission Labs were selected as our partner to build the first iteration of the application. Fission Labs is a software product development services company delivering product life-cycle management and high-end scalable technology solutions.

Introduction to the R Package `riskmetric`

in news

June 9, 2020

Many contributed R packages lack documentation expected in software qualification, which is required within pharma and other regulated industries. For pharma, there are various regulations, which require documentation that demonstrates software is used appropriately and works as expected. Thus, industry needs to establish appropriate requirements for R packages using selected metadata and useful risk metrics. In context of the R Validation Hub, the R package riskmetric has been developed, which seeks to take the first steps in identifying metrics and best practices to quantify the quality of R packages.
