Computation of Faber Series With Application to Numerical Polynomial Approximation in the Complex Plane

Kövari and Pommerenke [19], and Elliott [8], have shown that the truncated Faber series gives a polynomial approximation which (for practical values of the degree of the polynomial) is very close to ...

On optimal smoothing of density estimators obtained from orthogonal polynomial expansion methods

We discuss the application of orthogonal polynomials to the estimation of probability density functions, particularly with regard to accessing features of a portfolio's profit/loss distribution. Such ...
