Mathematical Methods of Statistics by Harald Cramér | Goodreads,Mathematical Methods in Statistics a Workbook: Freedman,Mathematical Methods in Statistics a Workbook: Freedman,Amazon.com: Mathematical Methods of Statistics. (PMS-9,Amazon.com: Introduction to Mathematical StatisticsHarald CramerIn this classic of statistical mathematical theory, Harald Cramér joins the two major lines of development in the field: while British and American statisticians were developing the science of statistical inference, French and Russian probabilitists transformed the classical calculus of probability into a rigorous and pure mathematical theory. The result of Cramér's work is a masterly exposition of the mathematical methods of modern statistics that set the standard that others have since sought to follow. For anyone with a working knowledge of undergraduate mathematics the book is self contained. The first part is an introduction to the fundamental concept of a distribution and of integration with respect to a distribution. The second part contains the general theory of random variables and probability distributions while the third is devoted to the theory of sampling, statistical estimation, and tests of significance.
