phasecalc: Phase from cosinor estimates

Description

Calculate the phase given the estimated sine and cosine values from a cosinor model.

Usage

phasecalc(cosine, sine)

Arguments

cosine

estimated cosine value from a cosinor model.

sine

estimated sine value from a cosinor model.

Value

• phaser
  Estimated phase in radians.

Details

Returns the phase in radians, in the range $[0,2\pi)$. The phase is the peak in the sinusoid.
