Hi, so the definition of however how do we define ie, when the condition is an inequality rather than an equality?

Thanks

Hey usagi_killer.

For the inequality condition what is done is we find a random variable that fits the definition of Y2 <= y2.

The easiest way to do this is have a double integral with the limits of Y2 going from -infinity to y2.

When you evaluate this double integral you will get an expression in terms of y2. - Feb 14th 2013, 07:18 PMusagi_killerRe: Conditional expectation with inequality
Thanks chiro, so what would the expression look like? Do we still use the conditional density function?

Would it be:

Yes that looks right.
