Slide the vertical scrollbars between $F_{ZW}(z,w)$ and $g(X,Y)$,$h(X,Y)$ to select the value of $z$. The plots will update according to that value. $F_{ZW}(z,w)$ will be the integral of $f_XY(x,y)$ in the regions where $g(x,y) < z$ and $h(x,y) < w$ (region showed in the $f_XY(x,y)$ plot). Use the lists bellow to change functions and densities.

Slide the vertical scrollbar between $F_Z(z)$ and $g(X,Y)$ to select the value of $z$. The plots will update according to that value. $F_Z(z)$ will be the integral of $f_XY(x,y)$ in the regions where $g(x,y) < z$ (region showed in the $f_XY(x,y)$ plot). Use the lists bellow to change functions and densities.

Slide the vertical scrollbar between $F_Y(y)$ and $g(X)$ to select the value of $y$. The plots will update according to that value. $F_Y(y)$ will be the integral of $f_X(x)$ in the regions where $g(x) < y$ (red region on the $f_X(x)$ plot). Use the lists bellow to change functions and densities.
