Consistent estimation of breakpoints in time series, with application to wavelet analysis of Citigroup returns

Roberts, Leigh - School of Economics and Finance, Victoria Business School - 2014

Simple and intuitive non-parametric methods are provided for estimating variance change points for time series data. Only slight alterations to existing open-source computer code applying CUSUM methods for estimating breakpoints are required to apply our proposed techniques. Our approach,...
