% This is the data set called `DETROIT' in the book `Subset selection in % regression' by Alan J. Miller published in the Chapman & Hall series of % monographs on Statistics & Applied Probability, no. 40. The data are % unusual in that a subset of three predictors can be found which gives a % very much better fit to the data than the subsets found from the Efroymson % stepwise algorithm, or from forward selection or backward elimination. % % The original data were given in appendix A of `Regression analysis and its % application: A data-oriented approach' by Gunst & Mason, Statistics % textbooks and monographs no. 24, Marcel Dekker. It has caused problems % because some copies of the Gunst & Mason book do not contain all of the data, % and because Miller does not say which variables he used as predictors and % which is the dependent variable. (HOM was the dependent variable, and the % predictors were FTP ... WE) % % The data were collected by J.C. Fisher and used in his paper: "Homicide in % Detroit: The Role of Firearms", Criminology, vol.14, 387-400 (1976) % % The data are on the homicide rate in Detroit for the years 1961-1973. % FTP - Full-time police per 100,000 population % UEMP - % unemployed in the population % MAN - number of manufacturing workers in thousands % LIC - Number of handgun licences per 100,000 population % GR - Number of handgun registrations per 100,000 population % CLEAR - % homicides cleared by arrests % WM - Number of white males in the population % NMAN - Number of non-manufacturing workers in thousands % GOV - Number of government workers in thousands % HE - Average hourly earnings % WE - Average weekly earnings % % HOM - Number of homicides per 100,000 of population % ACC - Death rate in accidents per 100,000 population % ASR - Number of assaults per 100,000 population % % N.B.
