Sažetak
The paper deals with the regression model, describes the procedure of getting regression coefficients and gives the analysis of the model variance. Chebyshev polynomials and their properties are also stated. The transformation of the regression model, from segment [a, b] to segment [-1, 1] is performed, as well as the approximation of the obtained regression polynomial, using prespecified accuracy polynomials of lower degree.
