Parametric interval linear systems are a class of mathematical models in which the coefficients of the matrix and the right‐hand side vector depend linearly on one or more parameters constrained ...

Differential equations are commonly used to model dynamical deterministic systems in applications. When statistical parameter estimation is required to calibrate theoretical models to data, classical ...

A class of parametric tests for heteroscedasticity in linear models is discussed. For models with nonstochastic regressors, new exact tests within this class are suggested which utilize existing ...
