Two Factor Analysis of Variance and Dummy Variable Multiple Regression Models
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
This paper proposes and presents a method that would enable the use of dummy variable multiple regression techniques for the analysis of sample data appropriate for analysis with the traditional two factor analysis of variance techniques with one, equal and unequal replications per treatment combination and with interaction. The proposed method, applying the extra sum of squares principl...

Global Stability of Stiers Impact on Meme Transmission Model
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
Spreaders and stiflers play a major role in the persistence or disappearance of memes. In this paper we study the impact of stiflers on the dynamics of memes transmission. We introduce and analyze qualitatively a mathematical model considering stiflers effect. Three equilibrium points of the model are examined: meme free equilibrium, meme cessation equilibrium and meme existence equilibr...

On Certain Bicomplex Duals
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
We investigated certain bicomplex duals of the class of bicomplex sequences defined by Srivastava & Srivastava [S2] and of the subclasses defined by Nigam [N1] and Wagh [W2]. Köthe & Toeplitz duals for bicomplex sequence spaces, defined and studied in [W3], have been extended further. Two types of duals namely αβ- dual and βα- dual have been defined and...

Further Results on Modified Variational Iteration Method for the Analytical Solution of Nonlinear Advection Equations
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 5
In this paper, the result shows that the method is elegant and reliable with less computational efforts. This method is strongly recommended for the solution of strongly nonlinear partial differential equations and systems of differential equations further to our results in [12] on the solution of nonlinear advection equations, we present a further results on the nonlinear non-homogeneou...

Ψ -Eventual Stability of Differential Systems with Impulses
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 6
In our paper, we have established criterion of Ψ-Eventual Stability for impulsive differential systems with variable moments of impulses by using piecewise continuous auxiliary functions which are analogous to Lyapunov’s functions. The work of Bainov, Kulev and Soliman has been extended. An example has been given to support the theoretical result. In the example, ...

On Certain Subclass of Analytic Functions Involving Generalized Derivative Operator
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 5
In this paper, a new subclass of analytic functions is introduced by means of a generalized derivative operator. Several properties like coefficient inequalities, growth and distortion theorems, convex linear combinations and radii of close-to-convexity, starlikeness and convexity of analytic functions belonging to the subclass are investigated. ...

Boundary and Sign Problems of Parameters along with its Solutions of the Augmented Dickey-Fuller Test
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 5
Usual test of testing unit root such as Dickey-Fuller (DF), Augmented Dickey-Fuller (ADF), Phillips Perron etc ignores sign and boundary of parameters. In this paper, we demonstrated the ignorance of sign and boundary of parameters and consequences of this ignorance in estimation and testing by Monte Carlo Simulation. Our main objective is to develop a method to capture the non-stationar...

Estimating Effects and Variance Components in Models of Quantitative Genetics in an Era Sequenced Genomes
Published In: GJSFR Part: F: Mathematics & Decision Volume: 14 Issue: 5
As in many other areas of research in genetics, the availability sequenced genomes in samples of individuals has revolutionized the study of quantitative traits, because researches have developed statistical evidence regarding the locations of genomic regions, loci, that have been implicated with the expression of a quantitative trait or traits. Therefore, in cases in which it is possibl...
