dhare

Hare: hazard regression

Description

Density (dhare), cumulative probability (phare), hazard rate (hhare), quantiles (qhare), and random samples (rhare) from a hare object.

Usage

dhare(q, cov, fit) 
hhare(q, cov, fit) 
phare(q, cov, fit) 
qhare(p, cov, fit) 
rhare(n, cov, 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.
`cov`	covariates. There are several possibilities. If a vector of length `fit\$ncov` is provided, these covariates are used for all elements of `p` or `q` or for all random numbers. If a matrix of dimension `length(p)`, `length(q)`, or `n` by `fit\$ncov` is provided, the rows of `cov` are matched with the elements of `p` or `q` or every row of `cov` has its own random number. If a matrix of dimension `m` times `fit\$ncov` is provided, while `length(p) = 1` or `length(q) = 1` or `n = 1`, the single element of `p` or `q` is used `m` times, or `m` random numbers with different sets of covariates are generated.
`fit`	`hare` object, typically obtained from `hare`.

Details

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

Value

Densities (dhare), hazard rates (hhare), probabilities (phare), quantiles (qhare), or a random sample (rhare) from a hare object.
