This function calculates the baseline hazard function for a fitted colsa
model and optionally provides confidence intervals for the estimated hazard.
Usage
# S3 method for class 'colsa'
basehaz(object, newdata = NULL, conf.int = 0.95, ...)Arguments
- object
An object of class
colsa. This is the fitted model object.- newdata
A numeric vector of time points at which to evaluate the baseline hazard. If
NULL, the function generates a sequence of time points based on the model's boundary.- conf.int
A numeric value between 0 and 1 specifying the confidence level for the confidence intervals. Default is 0.95.
- ...
Additional arguments (currently not used).
Value
A matrix with columns:
- time
The time points at which the baseline hazard is evaluated.
- basehaz
The estimated baseline hazard at each time point.
- se
The standard error of the baseline hazard estimates.
- lower
The lower bound of the confidence interval.
- upper
The upper bound of the confidence interval.
