## Introduction to Mathematical StatisticsAn exceptionally clear and impeccably accurate presentation of statistical applications and more advanced theory. Included is a chapter on the distribution of functions of random variables as well as an excellent chapter on sufficient statistics. More modern technology is used in considering limiting distributions, making the presentations more clear and uniform. |

Robert V. Hogg. Clearly, if x < 0, then F(x) = 0; and if x > 1 , then F(x) = 1 . Thus

we can write F{x) = 0, x2, = 1, x<0, 0<x< 1, 1 <x. Recall, in the discrete case, we

distributions. Since d approximates a, popular values of k to use are 1 .5 and 2.0,
