Dear all,
I am currently working on a mixed model with incorporation of knots at specific timepoints to compare the course over time between 5 different groups (cohorts).
Yet, I cannot figure out how I can retrieve the estimates of the intercept at these knots. And how to compare the intercept at these knots between the 5 groups.
Can anyone help me with this?
My mixed model:
mixed DAS28ESR i.cohort##c.years c.Age_incl i.sex ||EACNUMM: c.years, covariance(unstructured) reml
In which DAS28ESR is a measure for disease activity (continuous) and EACNUMM are the individuals.
Thanks in advance!
Kind regards,
Marloes
