Description

I am using Waves 7, 9 and 11 to conduct longitudinal analyses on changes in fruit and vegetable intake with age. I am using a multilevel (mixed effects) model where the measurement wave is level 1, individual (pidp) is level 2 and psu is level 3. I have looked through all the documentation and the other support cases (particularly Support #1572 ) but I have not found a solution on how to apply the survey weights to my model. I was advised to use the 'g_indscui_lw' weight for this analysis. The online documentation advises to use the 'survey' package in R but I am struggling to properly apply this to my multilevel model as the resources provided do not go into detail about this.

Any recommendations or advice you have on this would be greatly appreciated.
Many thanks
Tanya
