Hi, This is David from Bionic Turtle, and today we will be looking at the Quantile Function. The quantile function, which is the inverted cumulative distribution function, gives us the value (X) that answers the question, with confidence of (P%), what is the most losses I can expect?
The quantile function is not an idea in itself, but since it is an inverted function it tends to confuse most people. So to explain this concept, we have created a video that covers an example. You can watch this video here.
Here is the spreadsheet we have used (and that shows the same recursive solution to all three distributions): http://db.tt/gyrCxFU5
This brings us to the conclusion of the 5-Day Operational Risk Course. To know more about the full program (that's the one with the premium membership), click here.
