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
