13) ˆ fˆ(x) are vectors. 6 Empirical Application: Engel Curve Estimation A common problem in a variety of areas of economics is the estimation of Engel curves. 1. The subset contains 1,109 observations. We apply the moving average smoother with k = 51 to obtain the solid irregular line in the upper panel. The lack of smoothness is a feature of moving average smoothers. Note that the estimator does not quite extend to the boundaries of Introduction to Smoothing Model: y = f (x) + ε, x is log of total expenditure and y is the food share of expenditure.

For the time being, we will further assume that the xi are equally spaced on the unit interval. Define the estimator of f at xi to be the average of k consecutive observations centered at xi . 1) j= i where i = i − (k − 1)/2 and i¯ = i + (k − 1)/2 denote the lower and upper limits of summations. The estimator is of course equal to 1 fˆ(xi ) = k i¯ f (x j ) + j= i 1 k i¯ εj. 2) j= i If k – the number of neighbors being averaged – increases with n, then by conventional central limit theorems the second term on the right-hand side will be approximately normal with mean 0 and variance σε2 /k.

An algorithm used to implement local polynomial regression proceeds as follows: For a point xo find the k nearest-neighbors. These will constitute the neighborhood N (xo ). Define the span to be k/n. It is the fraction of total observations used in the local regression. Let (xo ) be the largest distance between xo and any other point in the neighborhood N (xo ). 2. Calculate the weighted least-squares estimator using the observations in the neighborhood and produce the fitted value fˆ (xo ). Repeat at the other values of x.
