Notes: Other parameters from these models (not shown) are similar to those shown in Table 3. Results based on average across estimates run on 40 imputed datasets. The average number of cases in each dataset was 771. Standard errors are estimated based on within- and between-imputation variances using Rubin’s rules. Significant differences (p<.05) between pairs of educational paths for a given growth factor are indicated by a shared superscripted letter.
