coxseifit.ex: CoxSEI model with exponential function

In coxsei: Fitting a CoxSEI Model

Description

Fit a CoxSEI model with exponential function to right censored counting process data

Usage

coxseifit.ex(dat, par.init, m = 2, mit = 1000, tr = TRUE,
             method = "L-BFGS-B",lower=c(rep(-Inf,ncol(dat)-3),-Inf,0),
             upper=rep(Inf,ncol(dat)-3 + 2),...)

Arguments

dat	The data
par.init	initial value of the regression coefficients and coefficients in the excitation function
m	the lag parameter (the m-dependence parameter)
mit	maximum number of iterations allowed in the optimizer
tr	whether to trace the optimization or not
method	the method of optimization used by the optim routine
lower	vector of lower boundary values of the parameter space
upper	vector of upper boundary of the parameter space
...	other arguments to be passed to the optimization routine

Value

A list of some components with kind of self-evident meanings by their name
