Hi there,

I'd like to age/sex/education match 3 groups (genetic status: Apoe4 Homozygote, Apoe4 heterozygote, non carriers). Currently, I am able to match two groups (i.e., Apoe4 Homozygote and Apoe4 heterozygote) on two demographic variables (sex and age), but I am having trouble extending this to match the three genetic status groups on age (continuous), sex (male/female/prefer not to disclose) and years of education (positive integer). Any syntax suggestions or guidance would be greatly appreciated!

Currently, my dataset comprises the following variable columns:
id
education (in yrs, integer)
sex (female, male, prefer not to disclose)
age (continuous)
geneticStatus ( response options: 1 = Apoe4 Homozygote, 2 = Apoe4 heterozygote, 3 = non carrier)

This discussion was helpful, but is only addresses 2 group levels (i.e., controls vs treatment), not 3.

Cheers,

Alex
