conditional distribution

In general, how do you find the distribution given x>c for some c? For example, what's the distribution of an exponential distribution given and ? Thanks(Nod)

Hello,

Use Bayes formula of conditional pdf (which is equivalent to that of conditional probabilities)
I'm not sure I'm guessing correctly what you mean... the distribution of what given X>c ?

Basically, I'm trying to find for some constant c where X is exponential. I thought maybe figuring out the distribution would help. Thanks (Wink)

Okay.

So you just have to translate the conditioning as "such that X>c", which gives , where is the pdf of X.
