thresh: Perform thresholding according to a tree

In treethresh: Methods for Tree-Based Local Adaptive Thresholding

Description

Thresholds according to a tree object of the classes treethresh or wtthresh.

Usage

## S3 method for class 'treethresh'
thresh(object, data, C, postmed=TRUE)
## S3 method for class 'wtthresh'
thresh(object, data, C, postmed=TRUE)

Arguments

object	An object of the class treethresh or wtthresh according to which thresholding is to be carried out.
data	The data to be thresholded. If object is of the class treethresh, then object has to be an array (or matrix) of exactly the same dimension as the data that was used to estimate object. If object is of the class wtthresh it has to be a list with elements of the same name and dimensions as the list that was used to estimate object. If no data object is given and if object is not estimated directly from the beta then the data used to estimate object is used.
C	If C is given then the tree is pruned with constant C (see the help of prune for details on the pruning).
postmed	If postmed=TRUE then the thresholding is done by returning the posterior median mu_i|X_i. If postmed=FALSE then hard thresholding is performed.

Value

thresh returns the thresholded data.

Note

For an example of the use of thresh, see coefficients.
