Title: Estimation Methods for Multivariate Linear Time Series

Keywords: Time series ; Multivariate ; Nonparametric
Abstract:

Nonparametric factor analysis techniques are used to create a low-dimension co-integration model for a multivariate time series with stochastic trend. The method of penalized least-squares is employed in order to obtain a closed-form estimate of the trend. Asymptotic results for the mean square error of the estimator are provided and the proposed procedures are applied to real time series data.
