CosAna – A Web Application
Cosinor analysis is a simple and popular method to analyze cyclic patterns. A sinusoidal pattern is fit to the data allowing to quantify the rhythm by mesor, amplitude and acrophase. A major advantage of this method is that the data does not have to be equidistant, and it can therefore also be applied to data with missing values.
Recently, a flexible and powerful online tool has been developed by ZWMB (Stefan Mendt) that allows quick and easy data preparation and fitting of circadian data.
