THE USE OF THE BOX-COX TRANSFORMATION, AN ALTERNATIVE TO THE QUADRATIC PRODUCTION FUNCTIONS

CIPRIAN RUJESCU, RAMONA CIOLAC, SIMONA CRISTINA MARTIN, MARIUS BUTUR

Abstract


This study pleads for the use of other alternative variants, flexible from the point of view of the mathematical expression, for the production functions in the case of determining the influence of fertilizing substances on cereal production. Practically, we examine the differences from the quadratic function, corresponding to a real situation of corn fertilization for a production function obtained by the Box–Cox transformation. The values obtained are very close, but in the context of a more flexible expression, they indicate the possibility of use for fertilization optimization issues.
