Tools for Estimating and Predicting the Cosinor Model R package cosinor version 1.2.3 A set of simple functions that transforms longitudinal data to estimate the cosinor linear model as described in Tong (1976). Methods are given to summarize the mean, amplitude and acrophase, to predict the mean annual outcome value, and to test the coefficients.
