lambda2Roy: Bivariate failure rate

In bivgeom: Roy's Bivariate Geometric Distribution

Description

Bivariate failure rate λ_2

Usage

lambda2Roy(x, y, theta1, theta2, theta3)

Arguments

x	observation from the first variable
y	observation from the second variable
theta1	paramater θ_1
theta2	paramater θ_2
theta3	paramater θ_3

Details

It is defined as P(X≥q x,Y=y)/P(X≥q x,Y≥q y). For this model, λ_2(x,y)=1-θ_2θ_3^x

Value
