Dear All: I am trying to compare points on two regression lines given some specific values of X. I am not sure how to do it in R and/or in SAS. Can someone help me, and show me how to conduct such test in R. You can use the following data for both lines. ### data for line 1: ### ========= x1<-c(0.0,0.25,2.5,25.0,50.0) y1<-c(100.0,79.0,74.0,36.0,8.0) ### data for line 2: ### =========
x2<-c(0.0,0.25,2.5,25.0,50.0) y2<-c(100.0,79.0,55.0,18.0,2.0) ### these are the given values of X: ### =================== x<-c(0.10,0.20,2.0,15.0,35.0) thank you very much in advance abou ========================== AbouEl-Makarim Aboueissa, Ph.D. Associate Professor of Statistics Graduate Program Coordinator Department of Mathematics & Statistics University of Southern Maine 96 Falmouth Street P.O.
