Cumulative Distribution Function

  Manoj       Wednesday, 27 July 2016


If $(X,Y)$ is a two dimensional random variable (discrete or continuous), then $F(x,y)=p\{X\le x\,andY\le y\}$ is called the cumulative distribution function of $(X,Y)$.

For discrete case,
F(x,y)=jiPij

yiy,xix


For continuous case,
F(x,y)=yxf(x,y)dxdy
