He used these results to determine the optimal design for estimating the individual coefficients in a polynomial regression model on the interval [-1; 1] explicitly. In this note we identify the optimal design for estimating the individual coefficients in a polynomial regression model with no intercept (here the regression functions do not form a Chebyshev system).enDiscussion Paper / SFB823;13/2019polynomial regressionc-optimal designChebyshev system310330620working paper
