Example of model fit (Tibolone group). Examples of estimated model components belonging to an animal of the Tibolone group, separated by experimental phase (P1 to P3). (a) Tail skin temperature time measurements (yn); (b) circadian components ; (c) amplitude functions ; (d) trend curves ; (e) combination of estimated circadian components and trend curves , embedded in the time series. Daytime periods are shown in yellow; nighttime periods are shown in blue. The model parameter estimates are given in the Tables 1 and 2.
