Description:
Provides tools to implement both unsupervised and supervised nonlinear dimension reduction methods. Principal Component Analysis PCA Sliced Inverse Regression SIR and Sliced Average Variance Estimation SAVE are useful methods to reduce the dimensionality of covariates. However they produce linear combinations of covariates. Kernel PCA generalized SIR and generalized SAVE address this problem by extending the applicability of the dimension reduction problem to nonlinear settings. This package includes a comprehensive algorithm for kernel PCA generalized SIR and generalized SAVE including methods for choosing tuning parameters and some essential functions.
