High-Frequency Quote Volatility Measurement Using a Change-Point Intensity Model

open access: yesMathematics, 2022
Quote volatility is important in determining the cost of demand in a high frequency (HF) order market. This paper proposes a new model to measure quote volatility based on the point process and price-change duration. Specifically, we built a change-point

Duration modeling with hidden Markov models [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1993
In hidden Markov modeling (HMM) of speech signals, the statistics of speech characteristics are represented by HMM parameters after the HMM training. This procedure is purely statistical. This study concerns the incorporation of explicit knowledge into the HMM training. Therefore one specific parameter, i.e., segment duration, was selected. In order to
