Introduction to Statistics and Econometrics covers probability and statistics, with emphasis on certain topics that are important in econometrics but often overlooked by statistics textbooks at this level… A thorough analysis of the problem of choosing estimators is given, including a comparison of various criteria for ranking estimators. The author also presents a critical evaluation of the classical method of hypothesis testing, especially in the realistic case of testing two composite hypothesis against each other.
