The data includes: # # I, the index; # A1, the average annual precipitation; # A2, the average January temperature; # A3, the average July temperature; # A4, the size of the population older than 65; # A5, the number of members per household; # A6, the number of years of schooling for persons over 22; # A7, the number of households with fully equipped kitchens; # A8, the population per square mile; # A9, the size of the nonwhite population; # A10, the number of office workers; # A11, the number of families with an income less than $3000; # A12, the hydrocarbon pollution index; # A13, the nitric oxide pollution index; # A14, the sulfur dioxide pollution index; # A15, the degree of atmospheric moisture. # B, the death rate. # # We seek a model of the form: # # B = A1 * X1 + A2 * X2 + A3 * X3 + A4 * X4 + A5 * X5 # + A6 * X6 + A7 * X7 + A8 * X8 + A9 * X9 + A10 * X10 # + A11 * X11 + A12 * X12 + A13 * X13 + A14 * X14 + A15 * X15 # # Modified: # # 08 November 2010 # # Reference: # # Richard Gunst, Robert Mason, # Regression Analysis and Its Applications: a data-oriented approach, # Dekker, 1980, pages 370-371. # ISBN: 0824769937. # # Gary McDonald, Richard Schwing, # Instabilities of regression estimates relating air pollution to mortality, # Technometrics, # Volume 15, Number 3, pages 463-482, 1973. # # Helmut Spaeth, # Mathematical Algorithms for Linear Regression, # Academic Press, 1991, # ISBN 0-12-656460-4. # 17 columns 60 rows Index A1 average annual precipitation in inches A2 average January temperature in degrees Fahrenheit A3 average July temperature in degrees Fahrenheit A4 percent of 1960 SMSA population 65 years old or older A5 household size, 1960 A6 schooling for persons over 22 A7 household with full kitchens A8 population per square mile in urbanized areas A9 percent nonwhite population A10 percent office workers A11 poor families (annual income under $3000) A12 relative pollution potential of hydrocarbons A13 relative pollution potential of oxides of Nitrogen A14 relative pollution of Sulfur Dioxide A15 percent relative humidity, annual average at 1pm.
