Unformatted text preview: We cannot compare two coefficients in the same model o The standardized slope, or beta weight, is standardized we can use this to compare relative influence of different variables Standardized slope: Beta weights o b* x1 = b x1 (s x1 /s y ) o The standardized slope tells us how many standard deviations y will change with a 1 standard deviation increase in x. o In the delinquency equation: b1 = 3.9; b*1=0.23 b2 = 2.05; b*2 = 0.579 Though the slope for age (b1) is larger, family attachment (b2) has a larger effect on delinquency Multiple coefficient of determination: R 2 o R 2 is just like Bivariate regression The proportion of variance in the dependent variable that is explained by all the independent variable Varies from 0 to 1 It tells us how good out model is, overall...
