In the numbering of the clusters, the first digit stands for the measuring point, and the digit after the hyphen numbers the clusters within a phase from 1 to 4.
1 For the additional variables, missing values were not imputed, so that the number of cases per cluster are in some cases lower.
2 Mirwald test, scale of 1 to 5; 1 = early development, 5 = late development
