SbivgeomRoy: Joint survival function

In bivgeom: Roy's Bivariate Geometric Distribution

Description

Joint survival function for Roy's bivariate geometric model

Usage

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

Arguments

x	vector of observations from the first variable X
y	vector of observations from the second variable Y (same length as x)
theta1	paramater θ_1
theta2	paramater θ_2
theta3	paramater θ_3

Value

The probability P(X≥q x, Y≥q y. For this model it is equal to S(x,y)=θ_1^xθ_2^yθ_3^{xy}
