RECURRENCE PLOTS

Dir sir： I use CRP toolbox ，i have some puzzle about the function ‘crp(x,m,t,e)’ and ‘pss’； e represent the threshold，but when i choose the norm ‘euclidean’，and set the e =2，like 'crp(x,3,1,2,'euclidean')',I noticed that there is a title on the picture ‘Dimention:3 Delay:1 threshold: 2σ’ ，i dont ko...

Dear all, For a noisy time series, it is mentioned in the literature that the threshold should be around 5*sigma. I wanted to ask if this sigma is the standard deviation of the time series? No, it is the standard deviation of the observation noise. This threshold value (5σ) is actually much too hig...

Dear sir: I am doing some research on bearing fault diagnosis by using RQA ,like the guy in the forum ，I am very confused about the selection of the threshold epsilion. so I use CWRU bearing fault data ，calculate the Normal bearing and faulty bearing's RPs,but I can't determine the threshold (i’ve s...
