**Unformatted text preview: **Y behave probabilis4cally – Characterized by density/probability mass func4on or distribu4on func4on • Condi4onal distribu4on of Y given X: how does Y behave, probabilis4cally, given that X is a par4cular value. Condi4onal distribu4ons: discrete case • P(Y=y | X=x) = pXY(x,y)/pX(x) – Condi4onal probability mass func4on • What would be the condi4onal distribu4on func4on? • For a given x, • Is the condi4onal probability mass func4on p(y|x) a probability mass func4on? And for densi4es? ...
