1. Least-Squares

Set 1

Given Function: y = 0.3745 + 0.98644x + 0.84564x^-1 Regression Function: y = 0.3745 + 0.9864x + 0.8456x^-1 R2: 0.9996

Set 2

Given Function: y = -11.4887 + 7.143817x - 1.04121x^2 + 0.046676x^3 Regression Function: y = -11.4887 + 7.1438x - 1.0412x^2 + 0.0467x^3 R2: 0.8290

Set 3

Given Function: y = 4.0046e^(-1.5x) + 2.9123e^(-0.3x) + 1.5647e^(-0.05) Regression Function: y = 4.0046e^(-1.5x) + 2.9123e^(-0.3x) + 1.5647e^(-0.05) R2: 0.9971
