If George W. Bush is sworn in as president even though Al Gore got more votes, Gore voters (including me) will be disappointed. But should we also feel aggrieved? Is it unjust? The truth is, not very. The electoral college used to drive...

Saddlepoint approximations are powerful tools for obtaining accurate expressions for densities and distribution functions. We give an elementary motivation and explanation of approximation techniques, starting with Taylor series expansions and progressing to the Laplace approximation of integrals. These approximations are illustrated with examples...
