Hi R users I want to use the lme package for a multilevel analysis on the following example: > math<-c(2, 3,2, 5, 6 ,7 , 7) > sex<-c(1, 2, 1, 2, 2, 2, 1) > school_A<-c(1,1,1,2,2,2,2) > school_B<-c(10,10,10,20,20,20,20) > mydata<-data.frame(math, sex, school_A, school_B) > mydata School_A and school_B are two different school characteristics, math is an individual score for each subject and sex is also an individual characteristic. Now i want to specify in R the following equations:
math=a +b *sex +error1 a= aa+ bb*school_A+ cc*school_B+ error2 b= aaa+ bbb*school_A+ ccc*school_B+ error3 but i don't know how. I searched nabble but could not find anything. Thank you and have a great day ahead [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
