The relevance of information theory to statistical theory and its applications to stochastic processes is a unifying influence in these TOPICS. The integral representation of discrimination information is presented in these TOPICS reviewing various approaches used in the literature and is also developed herein using intrinsically information theoretic methods. Log­ likelihood ratios associated with various stochastic processes are computed by an application of minimum discrimination information estimates. Linear discriminant functionals are used in the information theoretic analysis of a variety of stochastic processes. Sections are numbered serially within each chapter with a decimal notation for subsections. Equations examples theorems and lemmas are numbered serially within each section with a decimal notation. The digits to the left of the decimal point represent the section and the digits to the right of the decimal point the serial number within the section. When reference is made to a section equation example theorem or lemma within the same chapter only the section number or equation number etc. is given. When the reference is to a section equation etc. in a different chapter then in addition to the section or equation etc. number the chapter number is also given. References to the bibliography are by the authors name followed by the year of publication in parentheses. The transpose of a matrix is denoted by a prime; thus one row matrices are denoted by primes as the transposes of one column matrices (vectors).
