%description
Performs classification and variable selection on high-dimensional tensors
(multi-dimensional arrays) after adjusting for additional covariates
(scalar or vectors) as CATCH model in Pan, Mai and Zhang (2018)
<arXiv:1805.04421>. The low-dimensional covariates and the
high-dimensional tensors are jointly modeled to predict a categorical
outcome in a multi-class discriminant analysis setting. The
Covariate-Adjusted Tensor Classification in High-dimensions (CATCH) model
is fitted in two steps: (1) adjust for the covariates within each class;
and (2) penalized estimation with the adjusted tensor using a cyclic block
coordinate descent algorithm. The package can provide a solution path for
tuning parameter in the penalized estimation step. Special case of the
CATCH model includes linear discriminant analysis model and matrix (or
tensor) discriminant analysis without covariates.
