%0 Journal Article %T Modeling of Volatility with Non-linear Time Series Model %A Kim Song Yon %A Kim Mun Chol %J Quantitative Finance %D 2013 %I arXiv %X In this paper, non-linear time series models are used to describe volatility in financial time series data. To describe volatility, two of the non-linear time series are combined into form TAR (Threshold Auto-Regressive Model) with AARCH (Asymmetric Auto-Regressive Conditional Heteroskedasticity) error term and its parameter estimation is studied. %U http://arxiv.org/abs/1311.1154v2
