In this paper we revisit the notion that a single factor of duration running on single time scale is adequate to … capture the dynamics of the duration process of financial transaction data. The documented poor fit of the left tail of the … marginal distribution of the observed durations in some existing one-factor stochastic duration models may be indicative of the …

This paper extends a stochastic conditional duration (SCD) model for financial transaction data to allow for … correlation between error processes or innovations of observed duration process and latent log duration process with the aim of … estimation methods commonly used to estimate the SCD model in the literature, we work with the original specification of the …

the proposed TSCD model and MCMC method work well in terms of parameter estimation and duration forecasting. Lastly, the …This paper proposes a variant of a threshold stochastic conditional duration (TSCD) model for financial data at the … transaction level. It assumes that the innovations of the duration process follow a threshold distribution with a positive support …
