In Singular Spectrum Analysis (SSA) window length is a critical tuning parameter that must be assigned by the practitioner. This paper provides a theoretical analysis of signal-noise separation and reconstruction in SSA that can serve as a guide to optimal window choice. We establish numerical...

In this paper we propose a new methodology for selecting the window length in Singular Spectral Analysis in which the window length is determined from the data prior to the commencement of modeling. The selection procedure is based on statistical tests designed to test the convergence of the...

The purpose of our present study is to strike out suitable models to explain the growth pattern and to forecast for urban population in SAARC countries. Using the data from UNPD for the years 1950 to 2000 in five years interval, we fitted both exponential and ARMA models. We found the...
