Abstract
The key procedure of exploratory projection pursuit is to optimize a criterion function, which is called the projection pursuit index. The cook family index estimated by the wavelet kernel function is given in this paper. And the asymptotic unbiasedness and the convergence property of the projection index are proved. Also, as the fast computing of this kind projection index, it is suited for the processing of a large data. Some results of projection index based on the wavelet kernel estimation are compared with that of the Gauss kernel estimation.
