n cases = 414; ndyads = 29. marginal R2 = 0.039; conditional R2 = 0.082. Variance for the random factor DYAD = 0.003 ± 0.056 SD; GROUP = 0.019 ± 0.139 SD).
a
Not shown as not having a meaningful interpretation.
b
Estimate ± SE refer to the difference of the response between the reported level of this categorical predictor and the reference category of the same predictor.
c
These predictors were dummy coded, with the “Kinship (unrelated)”, Age class combination (same age)”, Sex class combination (same sex)”, “Mirror/No mirror (mirror)” being the reference categories.
