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.
