Selected Problems for High-Dimensional Data - Quantile and Errors-in-Variables Regressions.

... In the second part, we study matrix variate models (Dawid, 1981; Gupta and Varga, 1992) to explain two-way dependencies in data. Recent work on matrix variate models (Dutilleul, 1999; Lu and Zimmerman, 2005; Werner et ...

Empirical Tests of Asset Pricing Models with Individual Assets: Resolving the Errors-in-Variables Bias in Risk Premium Estimation

Empirical Tests of Asset Pricing Models with Individual Assets: Resolving the Errors-in-Variables Bias in Risk Premium Estimation

... We propose a method for estimating risk premiums using individual stocks as test assets. It overcomes concerns about risk premiums estimated with test portfolios, which have been employed in almost all previous ...

Robust Kalman filter and smoother for errors-in-variables model with observation outliers based on Least-Trimmed-Squares

Robust Kalman filter and smoother for errors-in-variables model with observation outliers based on Least-Trimmed-Squares

... Abstract— In this paper, we propose a robust Kalman filter and smoother for the errors-in-variables (EIV) state space model subject to observation noise with outliers. We introduce the EIV problem with ...
