Quantitative Risk Analysis with R

Duration: 4 full days
Minimum of 6 people and maximum of 15 people

Course overview

This 4-day course will cover the core principles of quantitative risk analysis and the most important risk modeling principles, methods and techniques. The course will be taught using the R statistical language but the lessons apply equally well to other modeling environments. The focus of the course is on how to conduct accurate and effective quantitative risk analyses, including best practices of risk modeling, selecting the appropriate distribution, using data and expert opinion, and avoiding common mistakes. The course will also cover essential probability and statistics theory and various stochastic processes to provide the participants with a solid understanding of quantitative risk analysis

Who should attend

Anyone in business, government and science with an interest in quantitative risk analysis such as professionals needing to perform quantitative risk analysis in epidemiology, finance or operations, engineering, project risk analysis and researchers who are involved in risk analyses. Also, people who have experience in risk analysis using spreadsheets but wants to learn how to use a more sophisticated modeling environment such as R.

Prerequisites

Participants are required to bring laptops loaded with R, and a pdf reader. R is an open-source freeware and can be downloaded free of charge from the R Project website. As R is updated constantly, please download the latest version before attending the course. Also, it is recommended participants use a text editor such as Tinn-R (Windows) to facilitate the display and storage of their code.

Prior experience using R or other simulation tools is not required

Teaching philosophy

All of EpiX Analytic's courses aim to help the participants understand risk analysis from the bottom-up, which is achieved through a relaxed, informal and interactive environment using plenty of examples and hands-on exercises where students apply and adapt what they have learned.

Free ModelAssist

ModelAssist is a comprehensive risk analysis training reference and is free of cost. This reference tool provides an in-depth explanation of all of the risk analysis concepts, techniques and methods introduced in this course and greatly complements the course material. ModelAssist can be downloaded directly from our website here.
