## 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. |

**Example**2. Let A , = {(x, y) : 0 < x = y < 1} and A2 = {(jc, y) : 0 < x< 1 , 0 < y < 1}. Since the elements of Ax are the points on one diagonal of the

square, then Ax a A2. Definition 2. If a set A has no elements, A is called the null

be meaningful, both x and y must be positive. Thus the space is the set s# = {(x,y):

x>0,y>0}. Definition 6. Let s/ denote a space and let A be a subset of the set s/.

**Example**15. Consider all nondegenerate rectangles of base x and height y. Tobe meaningful, both x and y must be positive. Thus the space is the set s# = {(x,y):

x>0,y>0}. Definition 6. Let s/ denote a space and let A be a subset of the set s/.
