## 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. |

We seek the p.d.f. g(y) of Y.

**Consider**the transformation y = x2. Thistransformation maps the space of X, si = {x: — oo < x < oo}, onto ^ = {y : 0 < y < oo

Thus, if we wish, we may

from the given distribution; and we may

sample of size a from the given distribution. We now define a + b + 1 statistics.

Thus, if we wish, we may

**consider**each row as being a random sample of size bfrom the given distribution; and we may

**consider**each column as being a randomsample of size a from the given distribution. We now define a + b + 1 statistics.

We now

denote a random sample of size n from a distribution that has a positive and

continuous p.d.f. /(x) if and only if a < x < b; and let F(x) denote the associated

distribution ...
