Hey, think I finished up here! I know its not the fastest way, but I stuck with what i knew how to do and actually made the CDF before finding the PDF. I found there to be three cases: w<0, 0<w<λ and λ<w. The first is trivially 0, the second one i integrated over (-w-λ to w-λ) and the third i...

Thanks for your help! Unfortunately, I'm still pretty confused. The leibniz rule makes sense (probably learned it at some point:) ) but I'm a bit confused about the rest still! First, I don't see how the heaviside step function helps in anything but a fairly trivial sense; is including it any...

Homework Statement Hi! I'm trying to find the PDF of W = abs(X-λ), where X is an exponential R.V. with rate parameter λ>0. Homework Equations The PDF for an exponential distribution is ∫λe^(-λx)dx. Taking the derivative of a CDF will yield the PDF for that function (I'm aware there are...
