Error or factorbSE(b)βtp value95% CI (b)
*Without constant using not forced backward stepwise linear regression method, step in p = 0.05 and out p = 0.10, adjusted after 10 iterations, adjusted R2 = 63%. Except errors, only factors reaching statistical significance at 0.10 level are shown.
b, non-standardized linear regression coefficient for the factor; SE(b), estimated standard error for b; β, standardized linear regression coefficient for the factor; t, t statistics value; 95% CI (b), confidence interval at 95% for b.
