Quantile graphs for the characterization of chaotic dynamics in time series
(Proceedings of 2015 IEEE World Conference on Complex Systems, WCCS 2015, 2016-06-01) [Trabalho apresentado em evento]
Recently, a map from time series to networks with an approximate inverse operation has been proposed [1], allowing the use network statistics to characterize time series and time series statistics to characterize networks. ...

Critical points on growth curves in autoregressive and mixed models
(Scientia Agricola, 2014-01-01) [Artigo]
Adjusting autoregressive and mixed models to growth data fits discontinuous functions, which makes it difficult to determine critical points. In this study we propose a new approach to determine the critical stability point ...
