An R package for assessing conjoint measurement properties in psychological and behavioral data. Provides tools for testing the axioms of additive conjoint measurement, enabling researchers to evaluate whether their measures have ratio or interval scale properties.

Status: In development

Stack: R

Automated Measurement Invariance Testing

An R project for automated measurement invariance testing across groups or time points, using lavaan as the modeling backend. Streamlines the sequential model comparison workflow (configural, metric, scalar, strict) with diagnostic output and decision support.

Status: In development

Stack: R, lavaan

Integrating Psychometrics and Machine Learning

Simulation Study

A simulation study comparing sum scores and raw item scores to latent variable EAPs and plausible values as inputs for ML prediction and classification in aging research. Investigates whether psychometrically informed scoring improves downstream ML performance.

Status: In progress

Stack: R
