RECURRENCE PLOTS

you can plot with or you can simply use the interactive mode of the function: (simply drop the left-hand output argument)

you can use the function crp2 in the CRP toolbox. this allows you to consider the x- and y-component as the dimensions of the phase space trajectory directly. if your data vector x is as you wrote with 1st column as time, 2nd column the x-component, and 3rd column the y-component, then you can do cr...

Hi Denise, interesting data, indeed! :D What you did is the construction of the joint recurrence plot. This is one possible solution. I am not sure why you have multiplied also the 2nd player with the 1st player. But when you simply multiply the RPs of the x- and y-component of the 1st player, this ...

Hi, when using the ACF, I would suggest to chose a delay where the ACF value falls below 1/e. Using MI, I agree with your selection of 200. Regarding your question on the selection for each time series: it depends on the research question. Without knowing more about the data and the research questio...

I would suggest to use the option "nonorm" to avoid the centering and standardisation of the data. When using embedding dimension of 1 the results should be the same for Euclidean and Maximum norm. The interpretation is similar but be aware that there is no phase space trajectory. We could...

There is nothing to be implemented further. If you have only a binary time series, you just need to ensure that your threshold is smaller than 1. This will give the same results as using the identity relationship (i.e., threshold = 0).

Yes, this is possible. This is also called "recurrence on a nominal scale" or "symbolic recurrences". There are several studies already using this approach. The difference to the standard recurrence approach is that instead of a neighbourhood of some size ε a recurrence can now b...

Thanks for your careful checking of the code. You are probably right! In the original version, the embedding used a fixed delay of tau = 1. Therefore, the considered line is a relict of these days. But as you said, it should be corrected to consider the delay. I will check the code and improve it wi...

I'm sorry but we provide the software for free and we have to manage it aside our daily work. If we would ask for money then I could understand that potential users might be unsatisfied with the delay. But not when we provide it for free. Moreover, in the email you have received after your request t...

great that it is now working. thanks for the reply.

I have just checked on a windows 8.1 system using Chrome and Firefox and it was working without any problems. As far as I understand you filled out all fields but have not been able to select the research field? Which entry have you tried to select? Did you try also other selections? You are the fir...

OK, I found an entry in the error log. There was a failure during registration. A database entry was not created. After your registration, have you seen a screen with a statement something like "registration success, access data will be send" or did you see an error message (or perhaps not...

Hello,

I'm sorry to read that you have not been able to download. But please let me know when did you registered? I can check in the database whether there have been some issues. We can surely help you.
