Author: Philipp Berens Email: berens@tuebingen.mpg.de Homepage: http://www.kyb.tuebingen.mpg.de/~berens/circStat.html If possible, please reference this page in your publication. Contents: circ_r resultant vector length circ_mean mean direction of a sample of circular data circ_std dispersion around the mean direction circ_var circular variance circ_dist pairwise distances around a circle circ_confmean confidence intervals for mean direction circ_rtest Rayleigh's test for nonuniformity circ_vtest V-Test for nonuniformity with known mean direction circ_mtest One-sample test for specified mean direction circ_wwtest Two-sample test for equal means circ_corrcc Circular-circular correlation coefficient circ_corrcl Circular-linear correlation coefficient rad2ang Convert radian to angular values ang2rad Convert angular to radian values All functions take arguments in radians (expect for ang2rad). For a detailed description of arguments and outputs consult the help text in the files. References: - N.I. Fisher, Statistical analysis of circular data, Cambridge University Press, 1996 - S.R. Jammalamadaka et al., Topics in circular statistics, World Scientific, 2001 - J.H. Zar, Biostatistical Analysis, Prentice Hall, 1999 The implementation follows in most cases 'Biostatistical Analysis' and all referenced equations and tables are taken from this book, if not otherwise noted. In some cases, the other two books were preferred for implementation was more straightforward for solutions presented there. Versions: Compared with an earlier version from 2006, the code has been cleaned up, some extra functionality and new tests have been added and some bugs removed. New features include confidence limits on the mean, the vtest, mtest, wwtest and corrcl commands for additional hypothesis testing and correlation analysis. If you have suggestions, feature requests or want to contribute code, please email me. Disclaimer: All functions in this toolbox were implemented with care and thoroughly tested on the examples presented in 'Biostatistical Analysis' were possible. Nevertheless, they may contain errors or bugs, which may affect the outcome of your analysis. I do not take responsibility for any harm coming from using this toolbox, neither if it is caused by errors in the software nor if it is caused by its improper application.
