Distribution of random quadratic forms arising in singular-spectrum analysis
V. G. Moskvina
Abstract
We derive explicit expressions for the coefficients of certain quadratic
forms arising in the singular-spectrum analysis, a novel technique of
time series analysis. We also derive expressions for the first two moments of these quadratic forms under the assumption that the time series is a sum of a linear trend and white noise.
Keywords
