The Nearest Polynomial of Lower Degree
"... Suppose one is working with the polynomial p(x) = −0.99B3 0(x)−1.03B3 1(x)− 0.33B3 2(x) + B3 3(x) expressed in terms of degree 3 Bernstein polynomials and suppose one has reason to believe that p(x) is really of degree 2. Applying the degree-reducing procedure [6] one gets −0.99B2 0(x) − 1.05B2 1( ..."

Suppose one is working with the polynomial p(x) = −0.99B3 0(x)−1.03B3 1(x)− 0.33B3 2(x) + B3 3(x) expressed in terms of degree 3 Bernstein polynomials and suppose one has reason to believe that p(x) is really of degree 2. Applying the degree-reducing procedure [6] one gets −0.99B2 0(x) − 1.05B2 1(x) + B2 2(x). But
