The objective of this work was to evaluate a group of twelve competition indexes through mathematical models adjusted with the minimum square procedure to estimate each distance independent index of competition to know the competitive status of the trees and forest stand; being this was a numeric relationship that shows in an indirect way the competition for limited resources in that site like: light, water and nutritious and also that both resources have a direct relationship with the growth and yield of the forest species, allowing us to obtain the best index for mixed species and to evaluate them based on their adjustment statistics and the efficiency of the estimators according to the hypothesis test practiced in the mathematical models. Of all evaluated indexes it was shown that the best index which was included in a model of prediction of the increment in diameter, was the index of crown width for density (IACD) because it presented the highest values in the test of ITI, with T = -6.637, also in the hypothesis test its level of accuracy, was highly significant Prob. > ITI = 0.0001.Keyworks: mathematical models, competition, mixed species.
