We are pleased to announce the opening of registration for our online R for Health Technology Assessment (HTA) showcase taking place on the 13:00-17:00 BST 9th October and 9:00-13:00 BST 12th October. Speakers from academia, government, industry, and consulting will give demonstrations of their R code solving specific challenges in HTA, ranging from patient level simulation and infectious disease modelling to propensity score weighting and expert elicitation. On 12th October 12:00-13:00 BST there will be a panel discussion on the value and challenges of using R in HTA, with Francois Maignen (NICE), Andrew Briggs (LSHTM), Liz Fenwick (Pharmerit), and Venediktos Kapetanakis (Evidera). Registration is free and can be complete at this link: https://r-hta.org/events/workshop/2020/ Note that you must register separately for each of the half-day events. PROGRAM Day 1. Showcase.
