Details

The original data contains the information of the mothers and children in the study for 28 days. Because of the weak serial correlation in the period of day 1 to 16, it is ignored. Only the period of day 17 to 28 is included here. To catch the specific characteristic of the mothers and children, the averages of the stress and illness status of them are added as new covariates; bstress and billness. While the covariates have no missing observation, responses have very low percentages of missing values, 0.97
