Terms and abbreviations related to
circadian rhythm
Description
Cosinor
Circadian rhythm analysis method introduced by
Halberg et al (1967).
MESOR
A circadian rhythm-adjusted mean based on the
parameters of a cosine function fitted to the raw
data.
AMP: Amplitude
Amplitude of a cosine curve best fitted to the
biological rhythm data.
Acrophase
Phase that represents the maximum value of a
cosine curve best fitted to the biological rhythm
data.
PR: Percent Rhythm
Rhythm compatibility
Squared multiple correlation coefficient (R)
between the measured value and the cosine
curve best fitted to the biological rhythm data.
