Table 2 The summary of chi-square statistics for the variance of random slope in different groups of individuals

From: Genotype effects contribute to variation in longitudinal methylome patterns in older people

  λmean/λmedian Number of probes with significant random slopes Largest χ2 Proportion of zero χ2 (χ2 < 10−5) (%) λmean/λmedian of non-zero χ2
All individuals 11.0/13.9 42,253 206.2 21.3 14.0/22.1
Individuals with 2 or 3 time points 7.9/9.6 20,291 139.1 21.3 10.0/15.5
Individuals with 4 time points 3.8/1.9 6729 128.2 30.6 5.4/5.9
