first.last.dh

Build special first/last database for some wavelet density functions

Description

This function builds a special first/last database for some of the wavelet density estimation functions written by David Herrick and described in his PhD thesis.

See first.last to see what this kind of function does.

Usage

first.last.dh(LengthH, DataLength, type = "wavelet", bc = "periodic",
    firstk = c(0, DataLength - 1))

Arguments

`LengthH`	The length of the smoothing (C) filter
`DataLength`	The length of the data that you wish to transform
`type`	The type of wavelet transform, `wavelet` or `station` for decimated and nondecimated transforms respectively.
`bc`	Boundary conditions, `periodic` or `symmetric`
`firstk`	The first k index, leave as default

Details

Description says all.

Value

A list with several components in exactly the same format as for first.last.
