Impact of Factor Rotation Methods on Simulation Composite Indicators
Journal Title: Mathematical Modelling and Analysis - Year 2011, Vol 16, Issue 3
Abstract
In this research one hypothesis about mathematical measure, which can be used as an additional tool for analysis and assessment Lithuania's economy tendencies, is verified. This additional measure has been constructed as a composite indicator (CI), involving indicators from social and economic fields. Simulated 45 different CIs have been obtained using several factor rotation methods. The analysis proved that standard mathematical methods may be used for composing CI, which give significant results analyzing Lithuania's economy state. Simulated CI during stable or growing periods have shown similar tendencies like GDP. Also our research proved that during crisis period different rotation methods may have influence on final results of CI.

A New Strategy for Choosing the Chebyshev-Gegenbauer Parameters in a Reconstruction Based on Asymptotic Analysis
The Gegenbauer reconstruction method, first proposed by Gottlieb et. al. in 1992, has been considered a useful technique for re-expanding finite series polynomial approximations while simultaneously avoiding Gibbs artifa...
Unsteady Squeezing Flow of a Viscous MHD Fluid Between Parallel Plates, a Solution Using the Homotopy Perturbation Method
The present paper analyses the unsteady 2-dimensional flow of a viscous MHD fluid between two parallel infinite plates. The two infinite plates are considered to be approaching each other symmetrically, causing the squee...
A Quasistatic Unilateral Contact Problem with Friction for Nonlinear Elastic Materials
The aim of this paper is to prove the existence of a solution to the quasistatic unilateral contact problem with a modified version of Coulomb's law of dry friction for nonlinear elastic materials. We derive a variationa...
Two-Sample Problems in Statistical Data Modelling
A common problem in mathematical statistics is to check whether two samples differ from each other. From modelling point of view it is possible to make a statistical test for the equality of two means or alternatively tw...
