6. Main results • Step 1: Estimating the coefficients of the model(Table 10.2,10.3). • Step 2: Examining how good the model predicts(Table 10.4,10.5). • Step 3: Hypotheses testing. • Tests about the equation(Table 10.6,10.7). • Tests about individual coefficients(Table 10.8,10.9). • Part and partial correlation coefficients. • Step 4: Checking for violations of regression assumptions. • Checking normality of the errors(Table 10.10,Figure 10.1,10.2). • Checking for homogeneity of variance of the residuals(Figure 10.3,10.4).
