This linear combination of the variables correlates much better than any of the single variables (Figure 4.2, left). The standardized regression coefficients...

The path coeffcients are standardized regression coefficients and are, therefore, directly comparable. 

Model complexity is defined as the sum of standardized regression coefficients ... 

The relative effectiveness and importance of the variables can be estimated from the relative magnitudes of the regression coefficients. This cannot be done directly on these coefficients, however, as their magnitudes are dependent on the niagnitudes of the variables themselves. In Equation (29), for example, the coefficient for the cubic term is small compared with those for the linear and quadratic terms, but the cubic term itself may be very large. Instead, the standardized regression coefficients, Bt, are employed. These are determined by... 

As expected, the relative significance of the standard regression coefficient B3 is considerably less than those of the standardized linear and quadratic coefficients, Bi and B2. 

These equations are illustrated graphically in Figure 5. As before, an ANOVA table can be constructed for each model and the significance of each term estimated by sums of squares decomposition and comparison of standard regression coefficients.

The beta coefficients (standard regression coefficients, Snedecor and Cochran, 1980) of the different species obtained from the multiple regression analysis of the data were in the order Fe, Mn oxide-bound = organic-bound > carbonate-bound (following the scheme of Tessier et al., 1979), indicating the importance of both Fe, Mn oxide-bound and organic-bound Cd species in estimating the CAI of the soils (Eq. (1), Table 17). In the scheme of Krishnamurti...

For each continuous variable (i.e. the first five listed), we present the standardized regression coefficient = the change in child IQ for a one standard deviation increase in the variable. For each binary variable (i.e. the next six listed) we present the change in child IQ for the feature being present compared with it being absent. In each case this is done after allowance for all other variables in the model... 

Figure 1 Relationships among variables affecting 6-month MDI/PDI, as revealed through structural equation analyses. Covariate-adjusted parameter estimates (and standardized regression coefficients) are indicated. All relationships significant at p = 0.05 or less, one-tailed tests. After Dietrich et al (1986)...
