RECURRENCE PLOTS

The eigth international recurrence plot symposium will be organized by the Jiangsu University in Nanjing, China, in August 21-23, 2019. The venue will be in Zhenjiang.

Hi Pier,

the empty region means that the states in this epoch do not occur at any other times. These state are unique. Perhaps you could also show us the time series?

No, it is not possible. The base of the CRP is the distance between two points (on two different phase space trajectories).

Yes, sure. As long as you don't delete the install.m file, you can use it several times, also at other machines.

Hi, I think nargoutchk was introduced before MATLAB R2006a. But it seems that your MATLAB is too old and does not have this function. I suggest to write simple function called nargoutchk.m and put it into the CRPtool folder: function out = nargoutchk(in1,in2) % do nothing By doing this you only lose...

Hi Mircea, you are right, when using the fixed number of neighbours (which is the original definition of an RP by Eckmann 1987) the RP is not symmetric. This should be clear because for recurrence pair i and j the k nearest neighbours of the state at time point i are not necessarily the k nearest ne...

Hi,

it depends on the data. I assume that you somehow normalized the data beforehand.

Then, only look at the RR. RR is the probability of recurrence with respect to some lag. Therefore, in your case, I would chose lag +15.

sounds more like feature extraction or support vector machines. I'm not an expert in this.

It is better to send me an email with all information I would need to figure out the problem. (MATLAB version, operation system etc)
Thanks!

Hello Fan.Mi, thanks for your kind words. Regarding your question: it is something different when you calculate the RQA for each of the N channels separately or when you combine all N channels to one phase space trajectory (of then dimension N ), because then you get only one RQA result. It depends ...

univariate means you analyse only one time series bivariate means you analyse two time series, e.g., correlation multivariate means you analyse more than one time series, usually more than two in your case, i guess you simply compare two time series, but all available pairs. your problem looks quit...

Hi,

no, you can only compare two time series with a CRP. But what is your research question? I guess that a bivariate test is mostly sufficient.

Hi Migul, great! Thanks for sharing the software and the code! I'm sure there are scientists who would like to use it. Perhaps you could add some instructions how to use the software and how to compile the source code and some note about the requirements to use the software (Win10?, 64bit?). I haven...

Hi Marina, the Theiler window corrects only the recurrences that are close to the reference point. All other, "futher away" points are not corrected. For a RP it means that the Theiler window is a small band along the main diagonal. Therefore, it will only partly affect the LAM measure. Be...
