Psi functions
1 2 3 4 5 | fn.psi.huber(u, k = 1.345, deriv = 0)
fn.psi.bisquare(u, c = 4.685, deriv = 0)
fn.chi.prop2(u, k = 1.345, deriv = 0, b = 0.71016)
|
u |
numeric vector of evaluation points |
k, c, b |
tunning parameters for each objective function |
deriv |
0 or 1: returns psi(x) or psi'(x) |
see psi.huber/psi.bisquare for more details. Note the difference in the returned value for deriv=0
for this package. Functions re-written out of convenience for the development of brlm.
