Despite the broad application of L.P. models in agriculture, enough attention has not been paid to the problem of validation of L.P. model's Technical Coefficients. In usual method of estimating these Coefficients, the
real characteristics of agricultural activities are not considered. The goal of this investigation was to promote the validity of technical coefficients in an L.P. model, through the application of regression methods. In this respect,
GLS and RCR methods were used. The results of the study indicated that with the application of these methods, the L.P. models can explain the
farmers' behavior better. The resulted optimal cropping patterns were more closer to actual cropping patterns, which supported the hypotheses that the
behaviors of peasant farmers in the study area were economical.
