Shiny App Showcase: Lucidum by Gary Hemming

Lucidum is an open source R Shiny app to help data scientists build and communicate GLMs and GBMs without writing code. Lucidum is designed to make model building more interactive, visual and insightful.
Lucidum was built using the “golem” package by ThinkR which made building and deploying the app a much more streamlined and enjoyable experience.
I originally wrote Lucidum to automate the repetitive tasks involved when building the types of regression models common to UK personal lines insurers. More recently, I have used it as a tool to help insurers move from GLMs to GBMs (specifically LightGBM), using SHAP values to understand and communicate model features and interaction effects.
I chose the name Lucidum as it is close to the latin word for “Shiny” and it contains the word “lucid” meaning ""easy to understand"
