DIC values for models fitted to the entire sample or to the participants with the highest PSST scores
| Model | Entire sample (n = 9)a |
Highest PSST scores (n = 3)c |
||||||
|---|---|---|---|---|---|---|---|---|
| NA | PA | quarrelsomeness | agreeableness | NA | PA | quarrelsomeness | agreeableness | |
| 1 (number of days per person) | –2,222 | –759 | –1,091 | –1,058 | –727 | –363 | –436 | –432 |
| 2 (number of social interactions) | –2,311b | –846b | –1,932b | –1,704b | –771b | –429b | –738b | –694b |
| 3 (moving average) | –2,336b | –855 | –1,925 | –1,697 | –787b | –425 | –739 | –697 |
| 4A (group dummy variables for phases of the menstrual cycle) | –2,334 | –850 | –1,919 | –1,692 | –790 | –427 | –734 | –700 |
| 4B (individual dummy variables for phases of the menstrual cycle) | –2,335 | –857 | –1,896 | –1,690 | –790 | –423 | –726 | –700 |
DIC, deviance information criterion; NA, negative affect; PA, positive affect; PSST, Premenstrual Symptom Screening Tool.
a
DIC values can only be compared for models on the same data [17]. The DIC values of NA are lower than those of PA, and this is due to more variation in the NA values compared to the PA values and not necessarily to a better model fit.
b
The decrease from the previous model exceeds 10.
c
Participants A to C.
