Local Adaptive Multiplicative Error Models for High-Frequency Forecasts (repl...
We propose a local adaptive multiplicative error model (MEM) accommodating time-varying parameters. MEM parameters are adaptively estimated based on a sequential testing... -
Missing in Asynchronicity: A Kalman-em Approach for Multivariate Realized Cov...
Motivated by the need for a positive-semidefinite estimator of multivariate realized covariance matrices, we model noisy and asynchronous ultra-high-frequency asset prices in a... -
Volatility of Price Indices for Heterogeneous Goods with Applications to the ...
Price indices for heterogeneous goods such as real estate or fine art constitute crucial information for institutional or private investors considering alternative investment...
