Random walks serve as fundamental models in the study of stochastic processes, simulating phenomena ranging from molecular diffusion to queuing networks and financial systems. Their inherent ...

An effective algorithm for solving large saddle-point linear systems, presented by Krukier et al., is applied to the constrained optimization problems. This method is a modification of skew-Hermitian ...

We propose an augmented estimating equation (AEE) approach for a semiparametric mean regression model with panel count data under possibly informative observation schemes and censoring. On a grid of ...
