Indra Bhan, Lal Shyam, Lal Shyam · Ratio mathematica · 2019
In this paper , nine new Legendre wavelet estimators of functionshaving bounded third and fourth derivatives have been obtained.Theseestimators are new and best approximation in wavelet analysis. Legendrewavelet estimator of a function f of bounded higher order derivatives isbetter and sharper than the estimator of a function f of bounded less orderderivative.
