Ten Things you should know about DCC
Caporin, Massimiliano; McAleer, Michael - Tinbergen Instituut - 2013
from diagonal BEKK in small systems; and DCC may be a useful filter or a diagnostic check, but it is not a model. … Conditional Correlation (DCC) representation for estimating and forecasting time-varying conditional correlations. The reasons … given for caution about the use of DCC include the following: DCC represents the dynamic conditional covariances of the …

Discussion of “Principal Volatility Component Analysis” by Yu-Pin Hu and Ruey Tsay
McAleer, Michael - Tinbergen Instituut - 2014
This note discusses some aspects of the paper by Hu and Tsay (2014), “Principal Volatility Component Analysis”. The key issues are considered, and are also related to existing conditional covariance and correlation models. Some caveats are given about multivariate models of time-varying...

Frontiers in Time Series and Financial Econometrics: An Overview
Ling, Shiqing; McAleer, Michael; Tong, Howell - Tinbergen Instituut - 2015
Two of the fastest growing frontiers in econometrics and quantitative finance are time series and financial econometrics. Significant theoretical contributions to financial econometrics have been made by experts in statistics, econometrics, mathematics, and time series analysis. The purpose of...

Stationarity and Ergodicity Regions for Score Driven Dynamic Correlation Models
Blasques, Francisco; Lucas, Andre; Silde, Erkki - Tinbergen Instituut - 2013
We describe stationarity and ergodicity (SE) regions for a recently proposed class of score driven dynamic correlation models. These models have important applications in empirical work. The regions are derived from sufficiency conditions in Bougerol (1993) and take a non-standard form. We show...

The Dynamic Skellam Model with Applications
Koopman, Siem Jan; Lit, Rutger; Lucas, André - Tinbergen Instituut - 2014
We introduce a dynamic statistical model for Skellam distributed random variables. The Skellam distribution can be obtained by taking differences between two Poisson distributed random variables. We treat cases where observations are measured over time and where possible serial correlation is...

Joint Bayesian Analysis of Parameters and States in Nonlinear, Non-Gaussian State Space Models
Barra, István; Hoogerheide, Lennart; Koopman, Siem Jan; … - Tinbergen Instituut - 2014
We propose a new methodology for designing flexible proposal densities for the joint posterior density of parameters and states in a nonlinear non-Gaussian state space model. We show that a highly efficient Bayesian procedure emerges when these proposal densities are used in an independent...

On the Invertibility of EGARCH
Martinet, Guillaume Gaetan; McAleer, Michael - Tinbergen Instituut - 2014
Of the two most widely estimated univariate asymmetric conditional volatility models, the exponential GARCH (or EGARCH) specification can capture asymmetry, which refers to the different effects on conditional volatility of positive and negative effects of equal magnitude, and leverage, which...
