  3. Econometrics, Models and Methodology

    Authors: Tewari, Devi D; Rao, V M;

    Reference No: CMA0696TEC Pages: 8 Published on: 1, January, 1990

    Abstract: This note defines what econometrics is. The differences between models and economic models are brought out. The six steps involved in econometric model building are (a) statement of theory of hypothesis, (b) specification of theoretical econometric model for testing theory, (c) estimation of the parameters of the model, (d) evaluation ...

  4. Some Basic Concepts of Statistics

    Authors: Tewari, Devi D; Rao, V M;

    Reference No: CMA0697TEC Pages: 6 Published on: 1, January, 1990

    Abstract: Statistics consist of two parts: descriptive and inferential. Knowledge of some basic statistical concepts is a prerequisite for developing deep into the theory of statistical inference and econometric analysis. Concepts like population vs. sample, parameters vs. statistics, and frequency distribution vs. probability distribution are brought out. ... More

  5. Statistical Inference: A Technical Note

    Authors: Tewari, Devi D;

    Reference No: CMA0699TEC Pages: 11 Published on: 1, January, 1990

    Abstract: Statistical inference is basically concerned with drawing conclusions about a population based on samples drawn from it. The probabilistic decision criteria are the very foundation of inferential statistics. The concept of hypothesis testing is presented in and this note is followed by discussion of properties of estimators, small and large ... More

  6. Data Summary Measures

    Authors: Tewari, Devi D; Rao, V M;

    Reference No: CMA0700TEC Pages: 12 Published on: 1, January, 1990

    Abstract: Various data summary measures are briefly discussed in this note. In the first section, various measures of location or averages are discussed, followed by a discussion on measures of data dispersion in the second section.

  7. Probability and Probability Distribution

    Authors: Tewari, Devi D;

    Reference No: CMA0701TEC Pages: 21 Published on: 1, January, 1990

    Abstract: This note introduces the concept of probability and probability distribution which is the backbone of statistical inference theory. Definition of probability, joint, marginal, and conditional probability distributions are provided and properties of probability distributions are outlined. Various sampling distributions which are used by econometricians are discussed in brief. ... More

  8. A Technical Note on Correlation Theory

    Authors: Tewari, Devi D; Rao, V M;

    Reference No: CMA0709TEC Pages: 5 Published on: 1, January, 1991

    Abstract: This note defines correlation and discusses various forms of correlations. Partial and rank correlations are also discussed, and an example is given to compute linear and rank correlation coefficients. ... More
