https://rdrr.io/rforge/fractal/ https://cran.r-project.org/web/packages/fractal/fractal.pdf Hi, I am trying to learn about nonlinear time series, and fractal time series analysis in particular. I am interested in becoming proficient with the 'fractal' package. I have two specific questions: 1. I have a basic understanding of ARMA and ARIMA models. Can someone recommend a good introductory text on nonlinear time series that emphasizes practical application? I am definitely not looking for a theoretical text on stochastic process. 2. Can someone point me in the direction of case studies where the 'fractal' package has been used to analyze the stock market? My main interests are in the DOW Transportation Index and the S&P500, but in the absence of these kinds of case studies I will happily study any practical case studies that utilize the 'fractal' package. Many Thanks in Advance, David Paul [[alternative HTML version deleted]]
