In a simulation, I am trying to find the value of $d_i$ where:
$\displaystyle d_i \sim \frac{\epsilon_i}{\lambda_i}$ where $\epsilon_i$ is i.i.d. exponentially distributed with parameter = 1 and $i=1...n$.
Conditional on $\lambda_i$ the $d_i$ have an exponential distribution of $\lambda_i$. I know the value of $\lambda_i$ but I don't know how to find the value of $d_i$. What are the steps should I undertake to find $d_i$? How relevant is the $\epsilon_i$?
