predict.ciregic function

Covariate-Specific Cumulative Incidence Prediction

predict method for class ciregic. It provides the predicted cumulative incidence function for a given covariate pattern and timepoint(s).

## S3 method for class 'ciregic'
predict(object, covp, times, ...)

Arguments

• object: an object of class ciregic, which is a result of a call to ciregic
• covp: a desired values for covariates
• times: time points that user wants to predict value of cumulative incidence function
• ...: further arguments

Returns

The function predict.ciregic returns a list of predicted values of the model from object. - t: time points

• cif1: the predicted value of cumulative incidence function for the event type 1

• cif2: the predicted value of cumulative incidence function for the event type 2

Details

predict.ciregic returns the predicted cumulative incidence function for a given covariate pattern and timepoint(s).

Examples

## Continuing the ciregic(...) example
pfit <- predict(object = fit, covp = c(1, 0.5), times = c(0.1, 0.15, 0.5, 0.7))
pfit
mint <- fit$tms[1]
maxt <- fit$tms[2]
pfit1 <- predict(object = fit, covp = c(1, 0.5),
                 times = seq(mint, maxt, by = (maxt-mint)/99))
plot(pfit1$t, pfit1$cif1, ylim = c(0, 1), type = "l")
lines(pfit1$t, pfit1$cif2, ylim = c(0, 1), lty = 2, col = 2)
