We establish the asymptotic theory for the estimation of adaptive varying-coefficient linear models. More specifically, we show that the estimator of the index parameter is root-n-consistent. It ...

A statistical measure of the linear relationship between two variables. The range of a correlation co-efficient is from -1 to +1. Variables with a positive correlation move in the same direction while ...
