Changepoint detection in random coefficient autoregressive models

Lajos Horvath, Lorenzo Trapani

We propose a family of CUSUM-based statistics to detect the presence of changepoints in the deterministic part of the autoregressive parameter in a Random Coefficient AutoRegressiv…

Sequential Monitoring of Changes in Housing Prices

Lajos Horváth, Zhenya Liu, Shanglin Lu

We propose a sequential monitoring scheme to find structural breaks in real estate markets. The changes in the real estate prices are modeled by a combination of linear and autoreg…

Change point detection in heteroscedastic time series

Tomasz Gorecki, Lajos Horvath, Piotr Kokoszka

Many time series exhibit changes both in level and in variability. Generally, it is more important to detect a change in the level, and changing or smoothly evolving variability ca…

Functional generalized autoregressive conditional heteroskedasticity

Alexander Aue, Lajos Horvath, Daniel Pellatt

Heteroskedasticity is a common feature of financial time series and is commonly addressed in the model building process through the use of ARCH and GARCH processes. More recently m…

On the asymptotic normality of kernel estimators of the long run covariance of functional time series

István Berkes, Lajos Horváth, Gregory Rice

We consider the asymptotic normality in of kernel estimators of the long run covariance kernel of stationary functional time series. Our results are established assuming a we…

Testing for independence between functional time series

Lajos Horvath, Greg Rice

Frequently econometricians are interested in verifying a relationship between two or more time series. Such analysis is typically carried out by causality and/or independence tests…
