摘要:The varying coefficient model is very popular in the application offinance, economics, medical science and many other areas, but the estimationand inference process are quite compute-intensive. This paper presents a localaverage method to reduce the computation burden. The estimation for the varyingcoefficients is discussed and is extended to the partially linear varyingcoefficient model. Furthermore, three tests are brought out to check whethercertain coefficient is constant or even significant. The proposed tests arevery easy to implement and their asymptotically distributions under nullhypothesis have been deduced. Simulations and real data application are alsostudied to illustrate the local average method.
