ExpoLogisticsurvival: Survival related functions for the Exponentiated Logistic(EL) distribution

Description

Conditional reliability function (crf), hazard function, hazard rate average (HRA) and survival function for the Exponentiated Logistic(EL) distribution with shape parameter alpha and scale parameter beta.

Usage

crf.expo.logistic(x, t = 0, alpha, beta)
hexpo.logistic(x, alpha, beta)
hra.expo.logistic(x, alpha, beta)
sexpo.logistic(x, alpha, beta)

Arguments

x

vector of quantiles.

alpha

shape parameter.

beta

scale parameter.

t

age component.

Value

crf.expo.logistic gives the conditional reliability function (crf), hexpo.logistic gives the hazard function, hra.expo.logistic gives the hazard rate average (HRA) function, and sexpo.logistic gives the survival function for the Exponentiated Logistic(EL) distribution.
