Hello everyone,

I was looking for a way to classify time-series based on the curve-fit. I try to campute several trends so i was thinking to link each trend with a function. increase with exponential for example, increase and decrease with a gaussian etc. The possiblities are endless though and it seems that is not always working well, especially if you work on small time-series (of 5-10 points only - one point in the end of the time-series can make the nls function to not be able to find the best fit among all these functions). Is there any package doing something similar? or another technique that could capture such trends? I can't find any code or publication on that, so I guess is something that is tested and is not working?

Any help is appreciated.

Best,
John
