Abstract In this article, we obtain explicit solutions of a linear PDE subject to a class of radial square integrable functions with a monotonically increasing weight function |x|e 2/2, β ≥ 0, x ∈ R. This linear PDE is obtained from a system of forced Burgers equation via the Cole-Hopf transformation. For any spatial dimension n > 1, the solution is expressed in terms of a family of weighted ge...

Every test especially recruitment exams must have reliability and validity in order to be reliable and adequate guide for organization’s leaders in making decisions.The present study aims at examining the predictive validity of IOOC employment test and its relationship with employees' performance in IOOC. The study population includes recruited employees in IOOC in 1385. The data was gathered u...

We consider the problem of sample size determination for count data. Such data arise naturally in the context of multicenter (or cluster) randomized clinical trials, where patients are nested within research centers. We consider cluster-specific and population-averaged estimators (maximum likelihood based on generalized mixed-effect regression and generalized estimating equations, respectively)...
