"WebJun 21, 2024 · 1 Yes the typical way is differentiation: f ( x, y) = ∂ x ∂ y F ( x, y). One must be careful in general cause a PDF doesn't always exist, but here taking this derivative will do the trick. (The discontinuity across the line x = 1 isn't a big deal. The support of the PDF just drops suddenly to zero when you cross into the half plane x > 1 .) Share " - Convert from cdf to pdf probability
