VPC in a three level random slopes model
Posted: Thu Dec 19, 2019 12:13 pm
Hello everyone,,
I am running a three-level growth curve with a random slope of age. I'm unsure whether the VPC should contain just the variance around the constant terms at each level, as follows:
display [RP2]var(cons)/([RP3]var(cons) + [RP2]var(cons) + [RP1]var(cons))
But should the random slope at level 2 also be included in calculations of the VPC??
