Re: threshold, delay,dimension

Hey, if you have the CRP toolbox (see: http://www.recurrence-plot.tk/programmes.php), you can use the mi function for finding a delay and the fnn function to find an optimal dimension. Finding an optimal threshold is more difficult and depends on the data under consideration. For more information se...

Significance of CRP/RP measures on a group level

Hello at all, sorry for the double post, I already posted this to the RP mailing list. I'm looking for some comments/recommendations about how to best determine the significance of CRP/RP measures on a group level. That is, I have a group of 50 test subjects where I calculated the CRP between 10 reg...

Re: Method of finding neighbours.

Hi, there is a nice review paper by Marwan et al. which explains the different types of norms: Marwan, N., Carmenromano, M., Thiel, M., & Kurths, J. (2007). Recurrence plots for the analysis of complex systems. Physics Reports, 438(5-6), 237–329. doi:10.1016/j.physrep.2006.11.001 Regarding RP an...

Re: JRP between binary and continuous time series

Thank you Norbert :). Did not look into this matter any further, but as soon as I do, I will post an update into this thread.

Confidence Intervals for RP-measures

Hi, I was wondering how to compute the confidence intervals for e.g. DET/LAM measures like mentioned in the following paper with the CRP toolbox or by using some functions from it respectively: Marwan, N., Schinkel, S., & Kurths, J. (2013). Recurrence plots 25 years later —Gaining confidence in ...

JRP between binary and continuous time series

Hi at all, I started to experiment with the crp toolbox (thanks for this nice toolbox btw) and want to apply RP to the analysis of fMRI data. I have two time series. The first consists of 1's and 0's and represents a stimulus on/offset and the second is a continuous time series consisting of fMRI da...
