ScaleCheck is a free, interactive Shiny app for checking the quality of psychological and behavioral scales. It gathers several psychometric methods into one place: descriptive statistics and reliability (Cronbach’s α, McDonald’s ω, GLB), dimensionality assessment (Parallel Analysis, Exploratory Graph Analysis,…
I designed computational tools for simulation-based assessment of statistical power, parameter bias, and confidence-interval coverage in structural equation models using the Multiple Indicators Multiple Causes (MIMIC) Quadruplets approach. quadSimple offers an accessible workflow for early instrument-development decisions, while quadSim supports more detailed simulations…
An end-to-end image-classification pipeline designed to distinguish alopecia, receding hairline, and no alopecia using Histogram of Oriented Gradients features and a support vector machine. The project includes standardized preprocessing, class balancing, multiclass evaluation, confidence scores, and an interactive Streamlit deployment…
A machine-learning project predicting the market value of Magic: The Gathering cards from characteristics such as rarity, type, release set, and other structured features. The workflow includes data collection and cleaning, exploratory analysis, feature engineering, regression modeling, performance evaluation, and…
Scry Magic is a free, local-first web app for Magic: The Gathering players. You upload photos or videos of your cards, and it identifies them; then you can organize a collection, build and analyze decks, and track prices. Card recognition…
I welcome collaborations on metascience, mental health, network analysis, psychometrics, educational assessment, open science, and reproducible quantitative research.
