Tools, Simulations and Repositories

FSIQ Stability Simulation - This repository includes a simulation of data using the known psychometric relationships between the WISC-V and WAIS-IV. This is based on a great blog post by Shane Costello which relied on the WISC-IV and WAIS-IV. The simulation covers all composites across the WISC-V and WAIS-IV. All outcomes rely on simulated scores, known correlations between tests, and known SEM for each score.

Psychology Test Visualisation Tool - This is a tool that has been developed to create visualisations of CHC assessment data and Conners-3 test data. Results from multiple testing dates can be compared. The tool is still under development. The repository can be found at Github
