n = 10 ; number of observations
randomize(17654321) ; sets random seed
beta = # (1, 2) ; defines intercept and slope
x = matrix(n)~sort(uniform(n)) ; creates design matrix
m = x*beta ; defines regression line
eps = 0.05*normal(n) ; creates obs error
y = m + eps ; noisy line
d = createdisplay(1,1)
dat = x[,2]~y
show(d, 1, 1, dat)| Subject: | XploRe: Learning Guide |
