Table 1 Summary of parameters in simulating missing data
Parameters | Details |
|---|---|
Missing rate | 5%, 10%, 15%, 20%, 30%, on behalf of the proportion of individuals with missing items |
The proportion of unit non-response and fixed item non-response | 0.2:0.8, 0.5:0.5, 0.8:0.2, on behalf of the probability of two different missing patterns |
Missing probabilities of the second-, fourth-, and sixth-week visits of the missing individuals | 30%:30%:40%, baseline was not set for missing |
Missing mechanisms | MCAR, MAR, MNAR |
Monotonicity | Monotonic and non-monotonic |
