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 (NAs) are allowed.

p

vector of probabilities. Missing values (NAs) 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.
