I need to fit a sinusoidal curve to
x-y data that exhibits a sinusoidal
pattern. The curve will be:
y = a*sin(w*x +p) ;
where I need to get the best
fit choice for the parameters
a, w, and p. Could anyone
suggest which package and
routine I should use? I have
less than 1000 data points.
Can this problem be somehow
coerced into a linear fit?
