Joint survival function
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 |
y |
vector of observations from the second variable |
theta1 |
paramater |
theta2 |
paramater |
theta3 |
paramater |
Value
The probability P(X\geq x, Y\geq y
. For this model it is equal to S(x,y)=\theta_1^x\theta_2^y\theta_3^{xy}
