Regression lines
My simpleminded understanding of simple regression is that when
plotting regression lines for x on y and y on x in the same plot, the
lines should cross each other at the respective means. But, given the
R function below, abline (lm(y~x)) works fine, but abline (lm(x~y))
does not. Why?
function () {
attach (attitude)
x <- rating
y <- learning
detach (attitude)
plot (x, y)
