tbs: The TBS Time Failure Distribution

In TBSSurvival: Survival Analysis using a Transform-Both-Sides Model

Description

Density function, distribution function, quantile function, random generation function and hazard function for the Transform-Both-Sides (TBS) model.

Usage

 dtbs(time,lambda=1,xi=1,beta=1,x=NULL,dist=dist.error("norm"))
 ptbs(time,lambda=1,xi=1,beta=1,x=NULL,dist=dist.error("norm"))
 qtbs(p,lambda=1,xi=1,beta=1,x=NULL,dist=dist.error("norm"))
 rtbs(n,lambda=1,xi=1,beta=1,x=NULL,dist=dist.error("norm"))
 htbs(time,lambda=1,xi=1,beta=1,x=NULL,dist=dist.error("norm"))

Arguments

time	vector of quantiles.
p	vector of probabilities.
n	number of observations.
lambda	parameter of TBS.
xi	parameter of the error distribution.
beta	parameter of the linear regressor.
x	vector/matrix of co-variables, x=NULL if there are not co-variables.
dist	Distribution of error, it can be string such as dist = "norm", "t", "doubexp", "cauchy" or "logistic, or it can also be given as a list of functions (density, distribution, quantile, random generation, name). Details below.

Details

The density function, distribution function, quantile function, random generation and hazard function for the failure time of a TBS Model. The distribution of error can be chosen from Normal, t-Student, Cauchy, Logistic and Doub-Exponential (Laplace), or can be given by the user (as long as it is zero-centered, unimodal and symmetric – TBS does not check it). See the help of dist.error for examples.

Value

‘dtbs’ gives the density, ‘ptbs’ gives the distribution function, ‘qtbs’ gives the quantile function, ‘rtbs’ generates random deviates, ‘htbs’ gives the hazard function.
