Usage 1

rpolyreg(xvector, yvector {, m}):

x

x data vector

y

y data vector: y[i] = f(x[i] {, x[i]^2, .., x[i]^m})

m

the regression (polynom) order; m>0 (default=1)

Result 1

A vector r with the m+1 coefficients or the regression polynom.

yREG[i] = r[0] + r[1]*x[i] {+ r[2]*x[i]^2 + r[m]*x[i]^m}
