WebDec 21, 2005 · Local polynomial regression is commonly used for estimating regression functions. In practice, however, with rough functions or sparse data, a poor choice of bandwidth can lead to unstable estimates of the function or its derivatives. We derive a new expression for the leading term of the bias by using the eigenvalues of the weighted … WebThe purpose of this assignment is expose you to a (second) polynomial regression problem.
