I have a dataset of 100 patients for whom data was recorded of 3 different parameters say Heart rate, temperature and ETCO2 levels which are measured in 3 phases eg. Phase 0, Phase 1 and Phase 2. The 3 parameters in each phase has multiple measurements taken as unequal time points in between phases.
eg. In phase 1,parameters have been measured at 0hr, 12hr, 24hr, 72hr, In phase 2 - 10mins, 20mins, 30 mins, In phase 3- 30 mins, 60 mins , 90 mins
In ideal situations, I would have used mixed methods ANOVA or LMM. But I am stuck with this.
Can anyone suggest what model would be best to do a between group and within subject analysis?
