Kernel Regression Estimation Using Repeated Measurements Data

The estimation of growth curves has been studied extensively in parametric situations. Here we consider the nonparametric estimation of an average growth curve. Suppose that there are observations from several experimental units, each following the regression model y(xi)=f(xj)+ε(j=1,…,n), where ε1, …, ε n are correlated zero mean errors and 0≤x1<…
