Heft: hazard estimation with flexible tails

Description

Density (dheft), cumulative probability (pheft), hazard rate (hheft), quantiles (qheft), and random samples (rheft) from a heft object

Usage

dheft(q, fit) 
hheft(q, fit) 
pheft(q, fit) 
qheft(p, fit) 
rheft(n, fit)

Arguments

`q`	vector of quantiles. Missing values (`NA`s) are allowed.
`p`	vector of probabilities. Missing values (`NA`s) are allowed.
`n`	sample size. If `length(n)` is larger than 1, then `length(n)` random values are returned.
`fit`	`heft` object, typically obtained from `heft`.

Details

Elements of q or p that are missing will cause the corresponding elements of the result to be missing.

Value

Densities (dheft), hazard rates (hheft), probabilities (pheft), quantiles (qheft), or a random sample (rheft) from a heft object.
