Regularized Sliced Inverse Regression

The archive regsir.zip contains R functions to perform regularization and shrinkage for Sliced Inverse Regression (SIR) as described in
  • Scrucca L. (2006) Regularized sliced inverse regression with applications in classification (2006). In "Data Analysis, Classification and the Forward Search", editors Zani S., Cerioli A., Riani M., Vichi M., Berlin, Springer-Verlag, pp. 59-66.
It also contains R functions to apply the method to DNA microarrays data as described in
  • Scrucca L. (2007) Class prediction and gene selection for DNA microarrays using sliced inverse regression (2007). Computational Statistics & Data Analysis, Vol. 52, pp. 438-451.
