Graphics in R


Do you like to learn how to produce statistical plots of data using the R language and environment for statistical computing and graphics?

We will cover the creation of standard plots such as scatterplots, bar plots, histograms, and boxplots and we will spend some time on the underlying model used to produce plots in R so that you can extensively customize these plots. We will also look at producing Trellis plots in R and how to customize them.

Finally, we will introduce the grid graphics system and look at producing unique plots from the ground up using basic components.

Learn all this and more with Dr. Paul Murrell’s online course Graphics in R at Statistics.com. For more details please visit at http://www.statistics.com/graphicsR/.  

Who Should Take This Course:
Anyone who needs to produce displays of data, whether for exploratory or confirmatory analysis. R graphics is particularly suited to producing publication-quality plots, so this course is particularly useful for anyone who needs to produce articles or reports or even web sites containing plots.

Course Program:

Course outline: The course is structured as follows

SESSION 1: Basic Plots
  • An overview of R Graphics
  • Functions for producing standard plots
  • Controlling colour, fonts, etc

SESSION 2: Customising Plots
  • Adding extra data or labels to a plot
  • Mathematical formulas on plots
  • Plotting multiple plots on a page

Interactive Data Visualization


A picture is worth a thousand words; less if it's a PowerPoint show, more if it's a good interactive data display.  Dr. Galit Shmueli covers the statistically-appropriate techniques and principles you can use to explore and investigate your data in "Interactive Data Visualization," statistics.com. For more details please visit at http://www.statistics.com/Visualization/.

Aim of the course:
"Interactive Data Visualization" is about the interactive exploration of data using state-of-the-art data visualization software. Participants will learn to explore a range of different data types and structures. They will learn about various interactive techniques for manipulating and examining the data and producing effective visualizations.

The course is very hands-on in terms of the learning process. Participants will be guided through an exploration of quantitative business data to discern meaningful patterns, trends, relationships, and exceptions that reveal business performance, potential problems and opportunities.

Who Should Take This Course:
Statistical analysts and data miners who need to explore and graph multivariate data, either to form impressions of the data or as a preliminary step to performing statistical tests or building models.

Course Program:

Course outline: The course is structured as follows

SESSION 1
  • Information visualization characterization and history
  • Elements of visual perception
  • Software introduction and data preparation (merging data, getting started, export)

Quantitative Risk Analysis


Risk is the handmaiden of economic activity.  Protection from risk was first offered as a separate product in Genoa in 1347, and is now a large industry in its own right. Attaching a value to risk is the province of risk analysis and risk modeling, the subject of Dr. Huybert Groenendaal's and Mr. Greg Nolder's online course "Introduction to Quantitative Risk Analysis," at Statistics.com. For more details please visit at http://www.statistics.com/risk/.

In this course you learn how to conduct accurate and effective risk analyses, including framing a risk analysis problem, best practices of risk modeling, selecting the appropriate probability distribution, using data and expert opinion, and presenting risk analysis results. In addition, the course will cover an introduction to probability and statistics theory and various stochastic processes, which are critically important to a solid understanding of quantitative risk analysis.

The course will also familiarize participants with risk analysis modeling environments (in this case @RISK, Crystal Ball and/or ModelRisk with Excel), but the lessons and techniques apply equally well to other modeling environments). The course will also cover common mistakes made when doing quantitative risk analysis and how to avoid them.

Who Should Take This Course:
