Correlated data summary

The correlated data summary provides information concerning the repeated measures specifications.

  • There is a single variable that identifies the subjects, so the number of subjects equals the number of levels of the subject effect.
  • There is also a single variable that identifies the repeated measurements; since the minimum and maximum number of measurements per subject equals the number of levels of the within-subject effect, this tells you there is complete information for each subject (the wheezing status for each child is recorded for each age level).
  • The dimension of the correlation matrix should equal the product of the levels of the within-subject effects.
