This paper deals with a class of estimators of finite population mean using a combination of two mixed classes of estimators by exploring the information on two auxiliary variables. We have assumed that the study variable y is highly correlated with both the auxiliary variables x...

Markov Models are very much popular in studying population dynamics subject to catastrophes. So, emphasis is given on a discrete state space models specically when the population change occurs as a result of births, deaths and immigration in presence of catastrophes. A transient...

This study examined the role of monetary policy mechanism in controlling inflation growth in Nigeria. Standardized Multiple Linear Regression Model (SMLRM) estimating technique was considered as a tool in fitting the model where inflation rate served as response variable and inco...

This paper solves in closed form the system of ODEs ruling the 2D motion of a gravity free double pendulum (GFDP), not subjected to any force. In such a way its movement is governed by the initial conditions only. The relevant strongly non linear ODEs have been put back to hypere...

In this paper, I have introduced half-metric spaces on normed vector spaces over \(\mathbb{R}\) or \(\mathbb{C}\), which are similar to metric spaces by relaxing a few conditions of metric space.I have also introduced even half-metric spaces,established some properties and discus...

In this paper, an SEIR epidemic model with nonlinear incidence is considered. First, we formulate the model and obtain its basic properties. Then, we find the equilibrium points of the model, the disease-free and the endemic equilibrium. The stability of disease-free and endemic...

Supplementary variables associated with the study variables have been identified to be helpful in improving the efficiency of ratio, product and regression estimators both at planning and estimation stages. The existing regression-based estimators are functions of regression slop...
