4. RESULTS AND DISCUSSION
Descriptive statistics of all variables and correlation matrix are shown in Table 2. For the examination
of multicollinearity problems, correlation coefficients between independent variables are analyzed.
The coefficients are smaller than 0.80 which reveals that there is no suspicion about multicollinearity
problems in this study (Hair et al., 2006). The variance inflation factors (VIF) for all variables, however,
are smaller than 10 which illustrates that the independent variables are not correlate with each other
(Neter et al., 1985).
