Singularities in bivariate normal mixtures

Yutaro Kabata, Hirotaka Matsumoto, Seiichi Uchida +1

We investigate mappings $F = (f_{1}, f_{2}) : R^{2} \to R^{2}$ where $f_{1}, f_{2}$ are bivariate normal densities from the perspective of singularity theory of mappi…

Algebraic approach to maximum likelihood factor analysis

Ryoya Fukasaku, Kei Hirose, Yutaro Kabata +1

In exploratory factor analysis, model parameters are usually estimated by maximum likelihood method. The maximum likelihood estimate is obtained by solving a complicated multivaria…
