To the vector belong the spoils: Circular statistics in Stata


  • Nicholas J. Cox

    () (Durham University)


Circular statistics are needed when one or more variables have outcome space in the circle, which is for example true for data measured with reference to compass, clock, or calendar. Applications abound in the earth and environmental sciences, not to mention economic and medical fields well represented among Stata users and other disciplines such as music. A talk on circular statistics was given in Boston in 2001. This update will survey the field with special reference to recently revised or newly written programs for graphics, summary, testing, and modeling.
