bandwidth.rq {quantreg}

bandwidth selection for rq functions

Description

function to compute bandwidth for sparsity estimation

Usage

bandwidth.rq(p, n, hs=TRUE, alpha=0.05)

Arguments

p

quantile(s) of interest

n

sample size

hs

flag for hall-sheather method

alpha

alpha level for intended confidence intervals

Details

If hs=TRUE (default) then the Hall-Sheather(1988) rule O(n^{-1/3}) is used, if hs=FALSE then the Bofinger O(n^{-1/5}) is used.

Value

returns a vector of bandwidths corresponding to the argument p.
