The scientific software for the rhythms analysis, time series analysis and forecasting.
This version, which has been tested and improved, offers many new features...
It combines the Exploratory Data Analysis approach (Tukey) applied to the graphical analysis of data in rhythmic phenomena and time series : Scatter plot, run sequence plot, lag plot, autocorrelation plot, Normality plot with powerful numerical statistical tests (K-S test, Q test, KW test et al.)
This version allows researchers to use the entire range of "Cosinor" methodology (Nelson, Bingham, Halberg) and the most complete (Confidence ellipses, modelisation, chronograms, polargrams, study of residuals, complete calculation of chronobiological, chronobiometrical or chronoeconometric parameters)
It also provides the most powerful different spectral analysis and periodograms :
Jenkins and Watts, Lomb and Scargle, Schwarzenberg-Cerny, Fourier, Burg MESA, Halberg, Gouthière: Reverse Elliptic, "Percent rhythm" to found periods. Features are offered such as :
Complex demodulations plots, transformation of previous data (log, arcsin and so on), removing linear or polynomial trend, filters, variance homogeneity plot of residuals, the graphs of Normality of residuals et al.
The nature of the data is not specific and can be of varied origin: biological, physical, economic et al. Data can be imported in the software editor, from Microsoft Excel or Cambridge Neurotechnology Actiwatch Standard and Light files. In the field, for example of actimetric studies, large data sets, e.g. more than 65,500 data points can be treated. The software also works well on short or simple data sets.
Download this fully functional and complete version (For PC Windows 98, ME, NT, 2000, Vista, XP 32, XP 64, W7 32, W7 64, W8, W9) including help in both English and French...
This software has been adopted as the best solution for rhythms time series analysis in research centers throughout the world...
