| Nonparametric frontier estimation assesses relative efficiency of production units. The method with a larger scope in the literature is Data Envelopment Analysis (DEA). Efficiency analysis evaluated by DEA demands special attention when selecting the variables of the model. This paper incorporated a reference matrix as preliminary step in the implementation of a variable selection method, to measure the efficiency of beef cattle production systems. With the assistance of specialists, this matrix aims refine a variable selection method, to reduce or put out the selection of worthless variables to a future efficiency analysis. Proposed method for DEA variables selection was scoped in eight cities in the western region of Rio Grande do Sul state, to evaluate... |
