Factor Structure of Sleep Complaints data set
SleepProblems.RdThis is a fictitious data set containing correlation matrices of five sleep-related variables.
Usage
data("SleepProblems")Format
A list with 2 elements.
- data
list. Contains correlation matrices of k=11 studies. Each correlation matrix has the same structure, and contains the variables "sleep quality", "sleep latency", "sleep efficiency", "daytime dysfunction" and "hypersomnia".- n
numeric. Sample size of each study.
Source
Fictitious data set. Data were simulated using the simulateData function in lavaan.
Details
This simulated data set can by used to fit a meta-analytic structural equation model using tssem1. It is assumed that
"sleep quality", "sleep latency" and "sleep efficiency" load on the latent factor "insomnia", while "daytime dysfunction" and "hypersomnia" measure the
latent factor "lassitude".
