    En este artículo se muestran los resultados de un estudio de comparación mediante simulación de tres técnicas de clasificación, regresión logística multinomial (MLR), análisis discriminante no métrico (NDA) y análisis discriminante lineal (LDA). El desempeño de las técnicas se midió usando la tasa de clasificación errónea. Se encontró que las técnicas MLR y LDA tuvieron un desempeño similar y muy superior a NDA cuando la distribución multivariada de las poblaciones es normal o logit-normal; en el caso de distribuciones multivariadas log-normal y Sinh-1-normal la técnica MLR tuvo mejor desempeño.

    In this paper we show the results of a comparison simulation study for three classification techniques: Multinomial Logistic Regression (MLR), No Metric Discriminant Analysis (NDA) and Linear Discriminant Analysis (LDA). The measure used to compare the performance of the three techniques was the Error Classification Rate (ECR). We found that MLR and LDA techniques have similar performance and that they are better than DNA when the population multivariate distribution is Normal or Logit-Normal. For the case of log-normal and Sinh-1-normal multivariate distributions we found that MLR had the better performance.
