Yoshio Takane is a psychometrician and quantitative psychologist (Emeritus Professor, McGill University), known for work on multidimensional scaling, constrained principal component analysis, and the theory linking latent-variable models for categorical data.
Key Contributions / Features
- Takane and de Leeuw (1987) — with Jan de Leeuw, the formal proof that the two-parameter normal-ogive IRT model and factor analysis of dichotomized variables share the same marginal likelihood, extended to ordered/unordered multicategory and pair-comparison data (IRT–Factor Analysis Equivalence).
- Broad contributions to multidimensional scaling and constrained/structured multivariate analysis.
