title: Suicides and the lunar cycle.
abstract: The existence of lunar influence on the frequency of suicide is tested by means of a permutation test. A total of 897 suicide deaths reported by the Anatomical Forensic Institute of Madrid were analyzed by a permutation test, a direct application of Fisher's ideas. Noteworthy in this study are the testing method used and the accuracy of timing of the deaths. Both factors provide firm ground for our conclusion: there appears to be no relationship between lunar phases and suicide.
