Method for obtaining the cumulative hazard function of a dfr_dist object.

Method for obtaining the cumulative hazard function of a dfr_dist object.

Usage

# S3 method for class 'dfr_dist'
cum_haz(x, ...)

Arguments

x

The object to obtain the cumulative hazard function of.

...

Additional arguments to pass into the integrate function (only used when no analytical cum_haz_rate is provided).

Value

A function that computes the cumulative hazard H(t) of the distribution. It accepts t, the time at which to compute the cumulative hazard, and par, the parameters of the distribution. If par is NULL, then the parameters of the dfr_dist object x are used. Finally, it passes any additional arguments ... to the rate function.

Details

If the dfr_dist object has an analytical cum_haz_rate function, that is used directly for fast, exact computation. Otherwise, numerical integration of the hazard function is performed.
