best polynomial approximation
Dear R-users,
I learned today that there exists an interesting topic in numerical
analysis names "best polynomial approximation" (BSA). Given a function
f the BSA of degree k, say pk, is the polynomial such that
pk=arginf sup(|f-pk|)
Although given some regularity condition of f, pk is unique, pk IS NOT
calculated with least square. A quick google tour show a rich field of
research
