Spillover effects of Great Recession on Hong-Kong’s Real Estate Market: An analysis based on Causality Plane and Tsallis Curves of Complexity–Entropy	2019-06-15		.txt	text/plain	5111	313	56	Based on permutation entropy, complexity–entropy causality plane and Tsallis complexity–entropy curve, we characterize the complexity of the housing indices-both in terms of size and region-and distinguish the level of informational efficiency. We start our analysis by presenting in Fig. 1, panel (a) and (b), the Shannon Complexity-Entropy Causality Plane (CECP) for all Real Estate indices in Hong Kong, partitioned by size and location. In order to compare the results, derived by the symbolic permutation entropy, with the Hurst exponent h, we generate a time series with the use of the fractional Brownian motion. In all cases but one, the indices, measured in terms of size and region, exhibit lower permutation entropy and higher complexity, meaning that the financial crisis event affected the dynamical structure of the indices, increasing their regularity and predictability. But the Kowloon index quantifiers exhibit higher permutation entropy value denoting greater informational efficiency or less regularity and loss of complexity.	./cache/cord-306014-tjnt01ld.txt	./txt/cord-306014-tjnt01ld.txt
