partially_nested_data_example
Description
An example dataset with the 2/1 partially nested design where the clustering is induced by treatment delivery. The example was based on the public-use data of the National Center for Research on Early Childhood Education Teacher Professional Development Study (2007-2011; for details about the study, see this [website](https://www.childandfamilydataarchive.org/cfda/archives/cfda/studies/34848/versions/V2)). The participants were assigned to either the treatment or control arms. The treatment arm was a one-on-one, web-mediated consultancy intervention in which the participants received online coaching from one of J = 12 coaches; that is, each coach represents a cluster in this example. The control arm participants had no such clustering.
