Description
The harmonic regression is usually fitted as
z(t) = mu + A*cos(2*pi*f*t) + B*sin(2*pi*f*t)
but is more meaningfully expressed as
z(t) = mu + R*cos(2*pi*f*t + phi),
where R and phi are the amplitude and phase.
This function converts the parameters in the R-phase form to the AB form.
Usage
1
RPhaseToAB(RPhi)
Arguments
RPhi
Vector containing the R and phi coefficients respectively.
Value
vector c(A, B)
