4. Modeling Assumptions in Regression
Review: Joint, Conditional, and Marginal Distributions
Let (X,Y) be a pair of random variables with joint density h(x,y)=x+y over the space [0,1]**2.
-What is the marginal density of X ? We denote this by writing h(x).
h(x)=
-What is the conditional density of Y given X=x? We denote this by writing .
h(x|y)=
