Format

• data.starts01a. A resimulated dataset containing three factors from the Big5 scale measured at five time points used in Luedtke, Robitzsch and Wagner (2018). The dataset only contains observations without missing data.

  'data.frame': 890 obs. of 16 variables:

• data.starts01b. Like data.starts01a, but the dataset also contains cases with missing data.

  'data.frame': 3215 obs. of 17 variables:

• data.starts02 contrains means and covariance matrices of the study of Wu (2016) for the older and the younger cohort (Table 2). Variables a indicate item parcels of negative attitude factor at six occasions. Variable b denotes the performance difficulty factor and variable c the somatic factor.
