Dear All R users:
I am teaching a statistical class. Can someone help me to write an R code to
compare two regression lines.
More specific, test the equality of slopes and
Y-intercepts (elevations). Please use this example of data.
Data for line 1:
============
X1<-c(25, 50, 100, 200, 400)
Y1<-c(77.7, 78, 64.3, 59.7, 51.2)
Data for line 2:
============
X2<-c(25, 50, 100, 200)
Y2<-c(77.7, 52.3, 23.7, 6)
With many thanks
Ali
