Subclaims¶
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? When individuals are classified via the membership model, few belong to the common variance model, implying traditional reliability indices potentially mask important individual variation. → Donald Williams 2021
Evidence¶
Donald Williams 2021¶
Donald Williams, Stephen Martin, Phillipe Rast. (2021). Putting the individual into reliability: Bayesian testing of homogeneous within-person variance in hierarchical models. Behavior Research Methods. https://doi.org/10.3758/s13428-021-01646-x
q2 · i? · associational · r?
Classification analysis using the article's membership model on the cognitive inhibition task data found that "few individuals belong to the common variance model". The article reports no effect size or count for this finding in the available text.
"We also find that few individuals belong to the common variance model, and thus traditional reliability indices are potentially masking important individual variation."
