Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Growth mixture models identified no distinct latent trajectory classes; a one-class solution fit best, with interindividual variation mainly in initial levels rather than growth rates. → Anna Widlund 2023

q2 · i? · associational · r2

Growth mixture modeling of 612 students across four time points (Grades 7–9) compared one- to four-class solutions using BIC, VLMR and entropy; "a one-class solution described the data best" (N = 612 per Table 2).

"The results revealed that a one-class solution described the data best. Although the entropy values indicated good classification accuracy for models with additional classes, the BIC continued to increase, indicating that the one-class model described the data best."
