Central Question

How much of later developmental outcomes is already determined by earlier states?

Overview

Predetermined R² is a novel index that quantifies the extent to which later development is determined by earlier developmental states. This concept sits at the intersection of developmental psychology, psychometrics, and statistical methodology — it requires developmental theory to frame the question, psychometric models to measure the constructs, and statistical methods to estimate the index. This cross-cutting nature makes it a uniquely integrative contribution.

Cross-cutting Research

This research integrates three fields: psychometric measurement, estimation theory, and developmental psychology.
