    2. Regression analysis.

    It is concerned with the study of dependence of one variable, the dependent variable, on one or more other variables, the explanatory variables, with a view to estimating and predicting the (population) mean or average value of the former in terms of the known or fixed values of the latter.

    AGRI ECONOMICS 

    SHORT QUESTIONS

    1. Econometrics.

    Social science in which the tools of economic theory, mathematics and statistical inference are applied to the analysis of economic phenomena.

    2. Regression analysis.

    It is concerned with the study of dependence of one variable, the dependent variable, on one or more other variables, the explanatory variables, with a view to estimating and predicting the (population) mean or average value of the former in terms of the known or fixed values of the latter.

    3. Correlation analysis.

    Closely related to regression analysis but here the primary objective is to measure the strength or degree of linear association between the two variables

    4. Co-efficient of determination.

    In two or multiple regression R2 is a summary measure that tells how well the sample regression line fits the data.

    5. Variation & variance.

    Variations mean the sum of squares of the deviation of a variable from its mean value. Variance is this sum of squares divided by the appropriate degrees of freedom

    Variation

    Variance = ——————————– d. f         

    6. Regression through the origin,

    Regression analysis in which the intercept term is absent or zero.
