Being able to simulate data allows you to:

  • prep analysis scripts for pre-registration
  • calculate power and sensitivity for analyses that don’t have empirical methods
  • create reproducible examples when your data are too big or confidential to share
  • enhance your understanding of statistical concepts
  • create demo data for teaching and tutorials

Installation

You can install the packages used in these tutorials and get a function that makes it easy to access the workshop .Rmd files by running the following code:

devtools::install_github("debruine/data-sim-workshops")

Load exercises with the following code:

dsw::exercise("faux")
dsw::exercise("calories")
dsw::exercise("fixed")
dsw::exercise("mixed")

Alternatively, download the stub files and install the specific packages for your workshop. They will be listed below under “Prep”.

Upcoming Workshops

Data simulation using faux

When: Wednesday May 24 15:00-17:00 (BST)
Where: RLadies Glasgow Register

This session will cover the basics of simulation using {faux}. We will simulate data with factorial designs by specifying the within and between-subjects factor structure, each cell mean and standard deviation, and correlations between cells where appropriate. This can be used to create simulated data sets to be used in preparing the analysis code for pre-registrations or registered reports. We will also create data sets for simulation-based power analyses. Students will need to have very basic knowledge of R and R Markdown, and have installed {faux}, {afex}, {broom} and {tidyverse}.
