Inferring multi-period optimal portfolios via detrending moving average cluster entropy (a)

P Murialdo, L Ponta, A Carbone - Europhysics letters, 2021 - iopscience.iop.org
Despite half a century of research, there is still no general agreement about the optimal
approach to build a robust multi-period portfolio. We address this question by proposing the …

Analysis of time series using a new entropy plane based on past entropy

G Qin, P Shang - Chaos, Solitons & Fractals, 2021 - Elsevier
Complexity is an important feature of complex time series. This paper proposes a new
entropy plane using past Tsallis entropy and past R e´ nyi entropy by weighted permutation …

Relative cluster entropy for power-law correlated sequences

A Carbone, L Ponta - SciPost Physics, 2022 - scipost.org
We propose an information-theoretical measure, the\textit {relative cluster entropy} $\mathcal
{D_ {C}}[P\| Q] $, to discriminate among cluster partitions characterised by probability …
