Quantlet: grlinreg2
Description: generates a graphical object which contains a linear regression plane from the data. The plane is computed on a rectangular grid with n^2 meshes.

Link:
Usage: gl = grlinreg2 (x, {n, {col}})
Input:
x m x 3 matrix
n 2 x 1 matrix
col color
Output:
gl composed graphical object

Example:

library ("graphic")

x  = normal(100,2)

y  = 3*x[,1]+5*x[,2]+normal(100)

l  = grlinreg2(x~y)

d  = createdisplay(1,1)

show(d,1,1,x~y,l)

Result:

shows the data and the linear regression plane
