String Patterns and Statistical Differences Between Two Groups of Strings

v0.5.1 · Feb 23, 2026 · MIT + file LICENSE

Description

Methods include converting series of event names to strings, finding common patterns in a group of strings, discovering "unique" patterns when comparing two groups of strings as well as the number and starting position of each pattern in each string, obtaining transition matrix, computing transition entropy, statistically comparing the difference between two groups of strings, and clustering string groups. Event names can be any action names or labels such as events in log files or areas of interest (AOIs) in eye tracking research. An R Shiny application is available on GitHub.
