Jointly continuous PDF Typically,when we want to actually compute this integral 0.4 we have to write it as an 0.2 iterated integral. -5 5 It is a good idea to draw a 0 0 picture of B to help do this. 5-5 Many sample observations are shown from a joint probability distribution.The marginal densities are shown as well. 10Jointly continuous PDF • Typically, when we want to actually compute this integral we have to write it as an iterated integral. • It is a good idea to draw a picture of 𝐵 to help do this. 10 Many sample observations are shown from a joint probability distribution.
