With dаtа frоm n = 39 individuаls frоm Peru, a regressiоn is done to analyze the relationship between Y = Systol, systolic blood pressure, and X1 = Age, X2 = Years (in urban area), X3 = FracLife, the fraction of life in urban area, X4 = Weight (in kg), and X5 = Chin, a measure of chin skinfold. We fit a multiple regression model, Y = β0 + β1X1 + β2X2 + β3X3 + β4X4 + β5X5 +ε, to the data with results as follows: Analysis of Variance Source DF Adj SS Adj MS F-Value P-Value Regression 5 4171.2 834.24 11.66 0.000 Error 33 2360.2 71.52 Total 38 6531.4 Coefficients Term Coef SE Coef T-Value P-Value Constant 109.4 21.5 5.09 0.000 Age -1.012 0.306 -3.31 0.002 Years 2.407 0.743 3.24 0.003 FracLife -110.8 27.3 -4.06 0.000 Weight 1.098 0.298 3.68 0.001 Chin -1.192 0.614 -1.94 0.061 Regression Equation Systol = 109.4 - 1.012 Age + 2.407 Years - 110.8 FracLife + 1.098 Weight - 1.192 Chin Note: Scatterplots and residual plots (not shown here) suggest no difficulties with these data or the model.
