Table 2. Goodness-of-fit results.

Chi-square/degree of freedom < 2 (good fit) and < 3 (acceptable fit); goodness-of-fit index > 0.95 (good fit) and > 0.90 (acceptable fit); adjusted goodness-of-fit index > 0.97 (good fit) and > 0.95 (acceptable fit); root mean square error of approximation < 0.05 (good fit) and < 0.08 (acceptable fit).
