This study compared the performance of some robust regression methods and the Ordinary Least Squares Estimator (OLSE). The estimators were compared using varied levels of leverages and vertical outliers in the predictors and the dependent variables. An anthropometric dataset on t...

In this paper, a fractional sub-equation method is proposed for finding exact solutions of the space–time fractional Burger’s equation and the space-time fractional fifth-order Sawda-Kotera equation. The derivative is defined in the Jumarie’s modified Riemann-Liouville sense. The...

In [1], C. Park generalized the notion of the quasi-normed space, i.e. he introduced the notion of the quasi 2-normed space. He proved several properties of the quasi 2-norm. In [2], M. Kir and M. Acikgoz gave the procedure of completing the quasi 2-normed space. Several inequali...

In the present paper, we consider relationships between the basic solution concepts of set-valued optimization, the properties of continuous multifunctions with compact and convex values and the existence of efficient continuous selections using the Maximum Theorem and the Distan...

In a Boolean ring, every element is trivially multiplicatively generated by idempotent elements. In this paper, we study the structure of rings in which certain subsets are multiplicatively generated by idempotents or multiplicatively generated by idempotents and nilpotents.

In the manuscript, a concept of a mixed monotone mapping is acquainted and a coupled fixed point theorems is substantiated for such nonlinear shrinkage mappings in partially ordered exact rectangular metric spaces. We enlarge and universalize the conclusions of these theory.

The class of Inverse Gaussian distributions is quite commonly used as a life-time model in reliability studies. The books by Chhikara and Folks [1] and Seshadri [2] present extensive discussions on classical inference for the parameters of Inverse Gaussian distribution. However,...
