The elaboration of the multi - factorial regression models for styding the economic eficiency of the autumn wheat in the district of Falesti, the Republic of Moldova

Abstract

The need for studying the economic efficiency of producing autumn wheat and also the reserves for increasing this efficiency requires the identification of the causal links between the factors which influence the indicators for the results in order to fundament decisions or make forecasts with respect to these factors in the future. In this way, the relations between the result indexes and the factors which influence the efficiency of the autumn wheat production can be brought together in the analysis of regression and correlation. Here we study the dependence between the result variable (characteristic) y and one or more independent variables (characteristics) x. The result characteristic y is also called the endogenous characteristic, dependent or effect, and the independent characteristic x – factorial, exogenous or causal.
