Table 1.
Number of measured variables: Latent factors (ratio) | Sample size, N | Degrees of freedom, df |
---|---|---|
10:2 | 286 | 34 |
15:3 | 147 | 87 |
20:4 | 97 | 164 |
25:5 | 70 | 265 |
30:6 | 56 | 390 |
35:7 | 47 | 539 |
40:8 | 41 | 712 |
45:8 | 35 | 917 |
50:10 | 31 | 1130 |
Note. The degrees of freedom were estimated using the formula by Rigdon (1994), where df = m* (m+ 1)/2 − 2 *m−ξ* (ξ− 1)/2 − B −Γ. RMSEA = root mean square error of approximation.
