tbs: The TBS Time Failure Distribution

Description

Density, distribution function, quantile function, random generation and hazard function for the TBS distribution.

Usage

dtbs(time,lambda=1,xi=1,beta=1,x=NULL,dist="norm")
 ptbs(time,lambda=1,xi=1,beta=1,x=NULL,dist="norm")
 qtbs(p,lambda=1,xi=1,beta=1,x=NULL,dist="norm")
 rtbs(n,lambda=1,xi=1,beta=1,x=NULL,dist="norm")
 htbs(time,lambda=1,xi=1,beta=1,x=NULL,dist="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, dist = "norm", "t", "doubexp", "cauchy" or "logistic".

Value

• `dtbs' gives the density, `ptbs' gives the distribution function, `qtbs' gives the quantile function, `rtbs' generates random deviates, `htbs' gives the hazard function.

Details

The density, 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).

Examples

ptbs(1,lambda=2,xi=1,beta=1,dist="norm")
