Thread: Arbitrage pricing theory with noise on excel

Hi I have to give an example of the arbitrage pricing theory for return not expected return so there will be some noise

How do I give an example on excel, do I just make a number up for the noise, or is there a formula for it?

Thanks

Buy a noisemaker?

if by noise you mean "i want to generate some random numbers", what distribution do you need the noise to follow?
