hard.thresh: Hard thresholding of a top-down Unbalanced Haar decomposition
In unbalhaar: Function Estimation via Unbalanced Haar Wavelets
hard.thresh R Documentation
Hard thresholding of a top-down Unbalanced Haar decomposition
Description
Presented with an object returned by best.unbal.haar, the function
sets to zero those Unbalanced Haar coefficients which fall below a certain threshold
sigma.
Usage
hard.thresh(buh, sigma = 1)
Arguments
buh
an object returned by best.unbal.haar containing the decomposition to be thresholded
sigma
the threshold (a positive scalar)
Value
a thresholded object, of the same class as buh

x.uh <- best.unbal.haar(x)
x.uh.th <- hard.thresh(x.uh)
x.uh.th.r <- reconstr(x.uh.th)
ts.plot(x.uh.th.r)
