I have time series of events. I observe that variance of inter-events intervals increases over the time.
Is it possible to detrend my time series?
Update:
Example of data is here. It is times when I observe event. Inter-events intervals are depicted below:
Just now I have the following solution:
1) I transform intervals($I$) to $log_{10}(I)$ 2) Then I simply detrend $log_{10}(I)$
Is it correct approach? Could you propose something more smart?
