tpchreg

Proportional hazards regression with piecewise constant hazards and tabular data.

Description

Proportional hazards regression with piecewise constant hazards and tabular data.

Usage

tpchreg(formula, data, time, weights, last, subset, na.action, 
contrasts = NULL, start.coef = NULL, 
control = list(epsilon = 1.e-8, maxit = 200, trace = FALSE))

Arguments

`formula`	a formula with 'oe(count, exposure) ~ x1 + ...'
`data`	a data frame with occurrence/exposure data plus covariates.
`time`	the time variable, a factor character vector indicating time intervals, or numeric, indicating the start of intervals.
`weights`	Case weights.
`last`	If `time` is numeric, the closing of the last interval.
`subset`	subset of data, not implemented yet.
`na.action`	Not implemented yet.
`contrasts`	Not implemented yet.
`start.coef`	For the moment equal to zero, not used.
`control`	list of control parameters for the optimization.

Note

The interpretation of cuts is different from that in hpch. This is intentional.

Examples

sw <- swepop
sw$deaths <- swedeaths$deaths
fit <- tpchreg(oe(deaths, pop) ~ strata(sex) + I(year - 2000), 
time = age, last = 101, data = sw[sw$year >= 2000, ])
summary(fit)
