The local linear regression technique is applied to estimation of functional-coefficient regression models for time series data. The models include threshold autoregressive models and functional-coefficient autoregressive models as special cases but with the added advantages such as depicting...

The varying-coefficient model is an attractive alternative to the additive and other models. One important method in estimating the coefficient functions in this model is the local polynomial fitting approach. In this approach, the choice of bandwidth is crucial. If the unknown curve is spatial...

Durante las últimas décadas se ha producido un creciente interés en nuestro país en relación a las economías regionales dada la necesidad de los gobiernos regionales de obtener información sobre sus economías para así llevar a cabo actuaciones de política económica más efectivas y...
