title: Time-series analysis--cosinor analysis: a special case.
abstract: Cosinor analysis provides an accessible means of evaluating and estimating the parameter of a cyclic phenomenon. Cosinor analysis does not require that the data be equal intervals without missing data. Cosinor analysis does require that the data can reasonably be considered to take the form of a deterministic cycle with a known period.
