Slutsky’s Theorem p 75TheoremIf X n converges <strong>in</strong> distribution to X and Y n converges <strong>in</strong> distribution (or <strong>in</strong>probability) to c, a constant, then X n +Y n converges <strong>in</strong> distribution toX +c. More generally, if f(x,y) is cont<strong>in</strong>uous then f(X n ,Y n ) ⇒ f(X,c).Warn<strong>in</strong>g: the hypothesis that the limit of Y n be constant is essential.Richard Lockhart (<strong>Simon</strong> Fraser University) <strong>STAT</strong> <strong>830</strong> <strong>Convergence</strong> <strong>in</strong> <strong>Distribution</strong> <strong>STAT</strong> <strong>830</strong> — Fall 2011 20 / 31
