Time Series Momentum [PDF]

open access: yesSSRN Electronic Journal, 2011
AbstractWe document significant “time series momentum” in equity index, currency, commodity, and bond futures for each of the 58 liquid instruments we consider. We find persistence in returns for one to 12 months that partially reverses over longer horizons, consistent with sentiment theories of initial under-reaction and delayed over-reaction.

Discrete-Valued Time Series

open access: yesEntropy, 2023
Time series are sequentially observed data in which important information about the phenomenon under consideration is contained not only in the individual observations themselves, but also in the way these observations follow one another [...]

The formulation of structural time series models in discrete and continuous time [PDF]

open access: yes, 1983
This paper sets out an approach for modelling univariate time series, including those in which observations are available on a daily basis. An underlying continuous time model is formulated and it is shown that this model has important implications for ...

On predictability of time series [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2019
The method to estimate the predictability of human mobility was proposed in [C. Song \emph{et al.}, Science {\bf 327}, 1018 (2010)], which is extensively followed in exploring the predictability of disparate time series. However, the ambiguous description in the original paper leads to some misunderstandings, including the inconsistent logarithm bases ...
