In this book, an attempt has been made to propose some new estimation procedures for the linear regression models such as elemental slopes methods, Grouping method, Hat diagonals method, and Dispersion and Correlation methods for estimating for estimating the parameters of the linear regression models....

In this some new estimation methods and testing procedures for the linear regression models with heteroscedastic disturbances. A Minimum Norm Quadratic Unbiased (MINQU) estimation method has been developed for estimating the unknown heteroscedastic error variances by using the weighted studentized residuals....

The study estimates efficiency magnitudes by applying LPP technic and compare them with their Stochastic Counterparts. The proposed study combines timeseries, cross section observations on Inputs, Input prices, outputs, derives factor minimal cost functions and formulates the Likelihood functions and maximise them to find MLEs of known parameters....
