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))

Value

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

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
