Functions used in connection with fitting of RCOX models

Description

This is an overview over core functions used in connection with fitting of RCOX models. The functions described here will typically not be directly called by the user.

Usage

scoring (m, K0, control = m$control, maxit=control$maxouter, trace = m$trace)
ipm     (m, K0, control = m$control, trace=m$trace)
matching(m, control=m$control, trace=m$trace)

Arguments

m An RCOX model object (an object of class rcox.Internal)
K0 An initial value for K
control A list controlling the fitting algorithms.
maxit Maximal number of scoring iterations
trace Controls various diagnostics print outs. A debugging feature not intended for the user.

Value

A list with fitted values (K, logL etc).

Examples

gm  = ~al:an:st
vcc = list(~me+st, ~ve+an, ~al)
ecc = list(~me:ve+me:al, ~ve:al+al:st)
data(math)

m1 <- rcox(gm=gm, vcc=vcc, ecc=ecc, data=math, fit=FALSE)
f1 <- matching(m1)

## Use f1$K as starting value
scoring(m1, K0=f1$K)
ipm(m1, K0=f1$K)
