rpolyreg

Linear, multivariant and polynominal regression.

Usage 1

rpolyreg(xvector, yvector):

x

x data vector

y

y data vector: y[i] = f(x[i])

Result 1

A vector r with the two linear regression coefficients.

yREG[i] = r[0] + r[1]*x[i]

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>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
