This work studies the inverse problem of reconstructing a time-dependent heat source in the heat conduction equation using the temperature measurement specified at an internal point. Problems of this type have important applications in several fields of applied science. By the Green’s function...

New design-based ratio and difference estimators of the distribution function are defined by minimizing the mean square error of a class of estimators. Proposed estimators do not assume a superpopulation model between the variable of interest and the auxiliary variable. Results derived from...

In this paper, we propose a simple test for the continuity of a distribution function or of the type of distribution. The main advantage of our test in comparison to others, as used in earnings-management studies, for example, is that no assumptions regarding the underlying distribution function...

In the study of earnings management, researchers attempt to know the reason managers manipulate earnings of a company. Some preceding studies have focused on the distribution of reported earnings, and they treat the evidence of manipulation on earnings as discontinuity (at most cases around zero...
