In robeth: R Functions for Robust Statistics

Computation of Li, li and lip

Description

See Marazzi A. (1993), p.282-286 and p.297-298

Usage

lrfctd(icase, y, ci, vtheta, offset, wa, ni, i0, i1, i2)

Arguments

icase	Integer: 1 for Bernouilli, 2 for binomial and 3 for Poisson.
y	The y vector.
ci	The c_i vector.
vtheta	The x by theta vector.
offset	The offset vector.
wa	The a_i vector.
ni	The integer n_i vector.
i0	Integer: 1 to compute Li otherwise 0.
i1	Integer: 1 to compute li otherwise 0.
i2	Integer: 1 to compute lip otherwise 0.

Value

List with the following components :

f0	NULL if i0=0 else Li.
i1	NULL if i1=0 else li , derivative of Li.
i2	NULL if i2=0 else lip, derivative of li.
sf0	NULL if i0=0 else sum of the Li components.
