|Spectral Plot for Sinusoidal Model|
We can make the following conclusions from the above plot of
the LEW.DAT data set.
This spectral plot shows a single dominant frequency. This indicates
that a single-cycle sinusoidal model might be appropriate.
If one were to naively assume that the data represented by the graph could be fit by the model
