Efficient Learning of Quadratic Variance Function Directed Acyclic Graphs via Topological Layers
Journal of Computational and Graphical Statistics, 2022 Directed acyclic graph (DAG) models are widely used to represent causal relationships among random variables in many application domains. This paper studies a special class of non-Gaussian DAG models, where the conditional variance of each node given its parents is a quadratic function of its conditional mean.

On the Maximization of Quadratic Weighted Kappa
Известия Иркутского государственного университета: Серия "Математика", 2018 An analytical expression for the optimal estimation of the numerical dependence by the criterion of a quadratic weighted kappa and also the expression for the optimal value of this criterion were obtained.
