Which method would you recommend to detect peaks from an exponentially distributed data?

Knowing that the data source is a "page views" quantity over time, and considering the following histogram (cropped, normalized), should I push further to determine the distribution underlying my data?

I am not sure I completely follow your question but which peaks do you want to detect? The mode for an exponential distribution is 0 which is also the peak. – Momo Oct 1 '12 at 1:08
The data on which I would like to perform peak detection seems to be drawn from a exponential distribution, yet I don't want to detect peak on this last one. – François Kawala Oct 19 '12 at 9:50
I still don't get what you are asking: If the data are drawn from an exponential distribution then they have as their theoretical mode the value of 0 (the point with the highest density). Or do you mean the point with the highest density for your sample? – Momo Oct 19 '12 at 12:33

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

For Peak Finding Criterion you can use one of the Detection/Intensity threshold, Slopes of peaks, Local maximum, Shape ratio, Ridge lines, Model-based criterion and Peak width methods.
