Frequency distribution of hospital-referred parasuicidal episodes in Edinburgh

This paper presents frequency distributions of parasuicidal episodes (suicide attempts) in Edinburgh for four subgroups of people for each of the years 1970, 1973, and 1974. Probability distributions are fitted to these data and it is shown that the log-series distribution best fits the data for two subgroups. The stability of the parameters of these distributions is examined and is demonstrated for two of the subgroups.
