Estimation of Population Ratio in Simple Random Sampling using Variable Transformation
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 4
This paper proposes six new estimators of the population ratio (R) of the population means of two variables (y and x) in Simple Random Sampling (SRS) scheme, using a variable transformation of the auxiliary variable, x. Properties of the proposed estimators, including optimality conditions, are derived up to first order approximation, and conditions under which the proposed estimators pe...

Helical–one, two, three–revolutional Cyclical Surfaces
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 4
This paper describes method for modelling of helical-n-revolutional cyclical surfaces. The axis of the cyclical surface 1 is the helix s1 created by revolving the point about n each other revolving axes (n = 1,2,3), that move together with Frenet-Serret moving trihedron along the cylindrical helix s. Particular evolutions are determined by its angular velocity and orientation. The moving...

Comparison of Numerical Schemes for Shallow Water Equation
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 4
Many problems of river management and civil protection consist of the evaluation of the maximum water levels and discharges that may be attained at particular locations during the development of an exceptional meteorological event. Numerical methods have become a useful tool to predict discharges and water levels in hydraulic systems. The shallow water or St. Venant equations, being a hy...

Some Further Developments in the Infinite Product Representation of Elementary Functions
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 4
An innovatory approach has been recently proposed for the derivation of infinite product representation of elementary functions. The approach is based on the comparison of different alternative forms of Green’s functions for boundary-value problems stated for the two-dimensional Laplace equation. A number of new infinite product representations of elementary functions wa...

A Logit Regression Analysis of Homeowners in Nigeria
Published In: GJSFR Part: F: Mathematics & Decision Volume: 13 Issue: 3
This paper studied the application of logit regression analysis to homeownership in Ado-Ekiti area of Ekiti State (Nigeria). The performance of the logit model in terms of classification of homeowners with respect to the average monthly income of some individuals was examined. The data of homeownership and income was fitted to the model by the WLS techniques. Result showed that the odds ...
