q2 · i? · associational · r2

Latent class regression on the longitudinal subset (n=95) assessed at end of 1st grade; the article reports "100% stability in class membership". A Monte Carlo simulation indicated power of 70–74% was acceptable for this sample size.

"Results (Figure 2 and Table 5) indicate that all of the children were classified to the same latent class in Year 2 as in Year 1, reflecting 100% stability in class membership."
