Table 1.

Measured parameters causing high multicollinearity within each variable type were introduced in the presented order and those with variance inflation factor (VIF) >5 were eliminated from subsequent multiple regression models. The subset that passed the VIF test (indicated by ✓) were included in multiple regression models.
