As in the presence of High leverage points (HLP) i.e. outliers, the ordinary least square (OLS) method does not provide true estimates of production function. In this study, the impact of HLP have been checked in case of linear and non linear production functions viz Quadratic function (QF),Square root function (SF) and Mitscherlich–Baule (MB), Cobb Douglas(CD) r...

The method of choosing the best boundaries that makes strata internally homogeneous as far as possible is known as optimum stratification. To achieve this, the strata should be constructed in such a way that the strata variances for the characteristic under study be as small as possible. If the frequency distribution of the study variable is known, the stratificati...

Ordinary least square method (OLS) is an efficient method for estimating the parameters under the presence of assumptions of error term. Moreover, the problems like multicollinearity, auto-correlation, outliers, influential observations, heteroscedasticity etc., do occur and then OLS estimates are less efficient. Under these conditions, different regression techniq...
