Call Abstracts for Contributed Talks

Thank you for sharing your knowledge and moving the R community forward!

We are now accepting abstract submissions for R-focused applications related to the below topics and industries. Accepted abstracts will be presented by the author at Meeting 2020, with an expected duration of 20-25 minutes in length (including a 5 minute question and answer period). It would be great if your talk belongs to one of the followings:

  1. Medicine, Public Health, Bioinformatics, Pharmaceutical industry
  2. Oil and Gas, Renewable Energy, Environment
  3. Business, Finance, Economics, Life, Social & Political Sciences
  4. Open data analysis & software development

Please submit a title and an abstract of at most 700 words (minimal 350 word counts) by March 31, 2020, to the organizing team via email. Chairs will review and notify of abstract acceptance. Note that you are required to register for the meeting before you can submit an abstract.

Workshop - Regression Diagnostics in R

John Fox, Professor Emeritus, McMaster University, Hamilton, Ontario, Canada

A regression model describes how the distribution of a response variable—or some characteristic of that distribution, typically its mean—changes with the values of one or more explanatory variables. Regression diagnostics are methods for determining whether a regression model that has been fit to data adequately represents the structure of the data. For example, if the model assumes a linear (straight-line) relationship between the response and an explanatory variable, is the assumption of linearity warranted? Regression diagnostics not only reveal deficiencies in a regression model that has been fit to data but in many instances may suggest how the model can be improved.

This workshop describes the implementation of common regression diagnostics in R, using functions in the basic R distribution and in the car and effects packages. Focusing initially on linear regression models fit by least-squares, I’ll discuss diagnostics for unusual data, including high-leverage points, outliers, and influential cases; problems with the distribution of the response variable, including non-normality and nonconstant error variance; nonlinearity, broadly construed as lack-of-fit; and (briefly) collinearity. I’ll also explain how most of these diagnostics can be extended straightforwardly to generalized linear models, such as logistic regression, and—time permitting—to linear and generalized linear mixed-effects models, and to linear models estimated by two-stage least-squares (the latter with the new ivreg package for R).

Most of the material for the workshop will be drawn from J. Fox, Regression Diagnostics, Second Edition (Sage, currently in press but to be published before the date of the workshop), and J. Fox and S. Weisberg, An R Companion to Applied Regression, Third Edition (Sage, 2019). Materials for the workshop will be made available at <tinyurl.com/Calgary-diagnostics>.
