Description Usage Format Source References

Data are simulated as part of a larger study (Curran et al., 2016; Curran et al., under review). Meant to simulate a dataset pooled across two studies, with 12 indicators and 3 moderators (age, gender, and study). Impact and DIF exist on the basis of these moderators.

1	data(xstudy)

A data frame with 500 rows and 25 columns. The 25 variables are:

ID: Unique identifier
AGE: Age in years, centered around age 13
GENDER: Effect-coded gender
STUDY: Effect-coded study membership
STUDYAGE: Interaction between age and study
TRUEETA: True score on latent variable for each subject – not used in analysis
STUDYETA: Interaction between study and score – not used in analysis
ZETA: Deviation score – not used in analysis
W: External covariate for original simulation – not used in analysis
Z1: External outcome for original simulation – not used in analysis
Z2: External outcome for original simulation – not used in analysis
Z3: External outcome for original simulation – not used in analysis
Z4: External outcome for original simulation – not used in analysis
