Hazard Function

Access a distribution's hazard function.

Usage

eval_hazard(distribution, at)

enframe_hazard(..., at, arg_name = ".arg", fn_prefix = "hazard", sep = "_")

Arguments

distribution, ...

A distribution, or possibly multiple distributions in the case of ....

at

Vector of values to evaluate the cdf at. Must be named when using in enframe_.

arg_name

For enframe_, name of the column containing the function arguments.

fn_prefix

For enframe_, name of the function to appear in the column(s).

sep

When enframe'ing more than one distribution, the character that will be separating the fn_name and the distribution name.

Value

The evaluated hazard in vector form (for eval_) and data frame or tibble form (for enframe_).
