Advanced R Workshop - May 20 and 21, 2010

We are pleased to announce the workshop "Advanced Statistical Modeling Using the Statistical Software Package R" on May 20 and 21, 2010. On both days, the workshop will take place between 8:30am and 4:30pm at the British Columbia Institute of Technology (BCIT), 555 Seymour Street, Vancouver, B.C. (This workshop is not affiliated with BCIT.)

What is R?

R is a free, powerful, open source software package with extensive statistical computing and graphics capabilities, which can be used to explore and analyze data. R shares many of its strong points with its commercial competitor S-PLUS. In addition to providing a comprehensive suite of conventional statistical tools, R has many freely available add-in packages which can be used to carry out more specialized statistical tasks. More information on R can be found on the website www.r-project.org.

Workshop Description

Day 1 on May 20th focuses on the use of R for linear regression modeling. You will learn appropriate R commands for building simple and multiple linear regression models and performing estimation and prediction on the basis of these models. By the end of Day 1 you will master the commands needed to perform simple and multiple linear regression analyses in R and be able to interpret the resultant R output.

Day 2 on May 21st is more advanced and deals with the use of R for building a range of advanced statistical models, including generalized linear models, generalized additive models, mixed effects models, ANOVA models, time series models and multivariate data models. You will learn appropriate commands for model selection, model fitting, model validation and model inference in various settings and become familiar with the interpretation of the corresponding R output. By the end of Day 2 you will be able to use R to solve a variety of advanced statistical modeling problems.

You can choose to attend both days or either day.

Benefits to Participants

After Day 1, you will be able to:

• Summarize and visualize your data prior to conducting simple/multiple linear regression analyses.
• Formulate simple/multiple linear regression models and fit them to your data.
• Interpret the parameters in simple/multiple linear regression models.
• Conduct statistical inference on these parameters by using confidence interval estimation and hypothesis testing.
• Use effective graphical methods for detecting violations of assumptions in simple/multiple linear regression analyses.
• Account for modeling-induced or pure residual autocorrelation.
• Detect multicollinearity and adopt measures for dealing with it.
• Use variable selection techniques to assess which variables should be included in a linear regression model and in what form.

After Day 2, you will be able to:

• Create appropriate plots of the data before and after fitting a model.
• Specify model formulae and model options in R.
• Use appropriate R functions for building generalized linear models, generalized additive models and mixed effects models, conducting analyses of variance, performing time series analyses, and carrying out multivariate analysis techniques.
• Display and interpret information about a fitted model and extract relevant R output.
• Assess the adequacy of a fitted model through appropriate model diagnostics.
• Adopt remedial actions when the adequacy of a fitted model is questionable, including data transformations, outlier removal and model updating.
• Use the fitted model as a basis for statistical inference.

Workshop Leader

The workshop is led by Dr. Isabella Ghement. Isabella obtained her Ph.D. in Statistics from the University of British Columbia (UBC) in 2005. Isabella has presented sold-out workshops on the statistical software package R to graduate students, researchers and others involved in cancer research, environmental and ecological research, biostatistics and bioinformatics. She also lectures part-time at the Sauder School of Business, UBC. Isabella has co-authored the publications "Seasonal Confounding and Residual Correlation in Analyses of Health Effects of Air Pollution" (Environmetrics, Vol. 18, Issue 4, June 2007, 375-394) and "Robust estimation of error scale in nonparametric regression models" (Journal of Statistical Planning and Inference, Vol. 138, Issue 10, October 2008, 3200-3216) and "Incorporating multiple interventions in meta-analysis: an evaluation of the mixed treatment comparison with the adjusted indirect comparison" (Trials, 2009 Sep. 21, 10:86).

Prerequisites

Day 1
Participants should have some basic knowledge of descriptive statistics, hypothesis testing and confidence intervals and familiarity with the statistical software package R and the Windows operating system.

Day 2
Participants should have an understanding of statistical modeling along with some basic knowledge of the statistical software package R and familiarity with the Windows operating system.

Participants should bring a laptop computer pre-installed with the free R software. Detailed instructions for downloading and installing R are available on our website at www.ghement.ca/Rinstructions.html.
