any good methods for estimating period for a very short time series, say, ar
ound 50 smaples.
It seems that Fourier transform does not give accurate estimation for very s
hort data. I am not sure whether wavelet may be a better way, but don't know
how to use wavelet based method for period estimation.
Thanks for your help! | j*******a

e a huge number of datasets.
