Re: [R] Fourier Row and spectral analysis

Hi, i have result from other program. Original serie have 225 observing, but program use only 224. the most domain frequencies are f1=1/224 f2=1/122 f3=1/74,66 f4=1/56 f5=1/24,88 When i know these frequencies a can do, new variable ,nubmers of variavle is 2*nubmer of frequencies: t-1:225

[R] Fourier Row and spectral analysis

Hello, i need to find in time serie, k=1,2,3...(how if possible) most domain frequencies and than smooth original serie by Fourier row y=mean + a1*Cos(2*pi/freq*t)+b1*Sin(2*pi/freq*t)+a2.. numbers a1,b1 ... i will have from simple regresion, i need only to find k msot domain frequensies a
