[R-sig-ME] equation for linear mixed model for repeated measures data

[Ahmad]

Hi

 

I have used "nlme" package in R for linear mixed model with repeated
measures using lme function (below):

 

model.1 <- lme(hta ~ group + days, data = dat, random = ~ 1 | id)

where is "hta" is the dependent variable, with 3 "groups" measured for 7
"days", and "id" is the induvial observations (subject) that were repeated
on for 7 days.

 

I am looking for the scientific question of this model for publication
(e.g.; yij = â0 + â1X1ij ,..) in "nlme" package, but couldn't find it. 

 

Any help comments would be greatly appreciated!

 

Ahmad
