About AGATe

The AGreement Analysis Toolkit (AGATe) is an application and associated reusable library (DLL) named AgreementRates.dll that supports the user-defined gesture elicitation methodology by calculating agreement rate statistics on data collected using this methodology. The methodology allows users to propose gestures to accomplish specified tasks in human-computer interaction, and final gesture sets are designed to maximize the guessability of the adopted gestures.

R Code for Agreement Rate Statistics

Download this "R-agreement.zip" archive for R code that implements simulation experiments to estimate the Type I error and power for a variety of statistical tests, including V_rd (Vatavu & Wobbrock, 2015), V_b (Vatavu and Wobbrock, 2016), the percentile bootstrap, and others, for comparing agreement rates in within- and between-subjects end-user elicitation studies. Our code uses Rand Wilcox's "Rallfun" R library for robust statistics. The main entry point of our code is the "main.R" file that runs all the simulation experiments.
