Question: Suppose that Y is discrete-valued, taking values only on the non-negative integers, and the conditional distribution of Y given X x is Poisson: P

Suppose that Y is discrete-valued, taking values only on the non-negative integers, and the conditional distribution of Y given X Æ x is Poisson:

Compute E[Y j X] and var[Y j X] . Does this justify a linear regression model of the formY Æ X0¯Åe?

Hint: If P
