The paper studies the notion of Stepanov almost periodicity (or S-almost periodicity) for stochastic processes, which is weaker than the notion of quadratic-mean almost periodicity. Next, we makeâ€¦ (More)

In this paper we use the well-known Schauder fixed point principle to obtain the existence of square-mean almost periodic solutions to some classes of nonautonomous second order stochasticâ€¦ (More)

This paper concerns the square-mean almost periodic solutions to a class of nonautonomous stochastic differential equations on a separable real Hilbert space. Using the so-calledâ€¦ (More)

Incomplete data are common phenomenon in research that adopts the longitudinal design approach. If incomplete observations are present in the longitudinal data structure, ignoring it could lead toâ€¦ (More)

The problem of incomplete data is a common phenomenon in research that involves the longitudinal design approach. We investigate and develop a likelihood-based approach for incomplete longitudinalâ€¦ (More)

The paper studies a Beverton-Holt difference equation, in which both the recruitment function and the survival rate vary randomly. It is then shown that there is a unique invariant density, which isâ€¦ (More)

In clinical trials, several competing treatments are often carried out in the same trial period. The goal is to assess the performances of these different treatments according to some optimalityâ€¦ (More)
