denoiseR: A Package for Low Rank Matrix Estimation.

Summary We present the R package denoiseR dedicated to low-rank matrix estimation. First, we briefly review existing methods including singular value shrinkage and a parametric bootstrap approach. Then, we discuss how to extend the methods to missing values and suggest a general iterative imputation algorithm. It includes an extension of the Stein Unbiased Risk Estimate to missing values for selecting tuning parameters. Finally, we compare and apply the methods with many experiments.
