Multivariate linear regression analysis with patient dissatisfaction as outcome*
| Error or factor | b | SE(b) | β | t | p value | 95% 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. | ||||||
