lsa {eatRep}

Achievement data from two large-scale assessments of 2010 and 2015.

Description

This example data set contains fictional achievement scores of 11637 students from three countries and two times of measurement in two domains (reading and listening comprehension) in the long format. The data set contains nested multiple imputed plausible values of achievement scores as well as some demographic variables. Illustrating trend analyses, data from two fictional time points (2010 and 2015) are included.

The data set can be used for several illustration purposes. For example, if only multiple imputation should be considered (without nesting), simply use only cases from the first nest (by subsetting). If only one time of measurement should be considered (i.e., without any trend analyses), simply choose only cases from 2010 or 2015. If only reading or listening should be considered, choose the desired domain by subsetting according to the domain column.
