| description | The estimates of dominant height or site index allow evaluating the productivity of forest stand and function as tool within the forest management plan for harvesting purposes. This work aimed to analyze dynamic site index curves with the generalized algebraic difference approach (GADA) in 12 Forest Management Units for Abies religiosa in different regions of Mexico. 262 stem analysis samples from dominant and codominant trees were used, which were fitted with the Richards model using the GADA by ordinary least squares. With this approach, the parameters of growth rates and asymptotes can be expanded, allowing more than one parameter of the model to depend on the quality of the site, making polymorphic curves with multiple asymptotes more flexible. Autocorrelation was also corrected using the Durbin Watson (DW) statistical test. In general, significant gains were obtained for all sites, obtaining errors of less than 1.2 m and adjusted coefficients of determination that explain more than 97% of the total variance of growth in height as a function of age, as the DW values approximate to 2 in which it rectifies the values provided by Akaike information criteria, which is desirable for modeling growth trend data without affecting site index predictions. The equations are recommended to develop management plans for this species at different sites to classify timber productivity. |

Las estimaciones de altura dominante o índice de sitio permiten evaluar la productividad del rodal del bosque y funcionan como una herramienta dentro del plan del manejo forestal para fines de aprovechamiento. Este trabajo tuvo como objetivo analizar curvas dinámicas de índice de sitio con el enfoque de diferencia algebraica generalizada (EDAG) en 12 Unidades de Manejo Forestal para Abies religiosa en diferentes regiones de México. Se utilizaron 262 muestras de análisis troncales que provienen de árboles dominantes y codominantes, mismas que se ajustaron con el modelo de Richards mediante el enfoque EDAG por mínimos cuadrados ordinarios. Con este enfoque pueden ser expandidos los parámetros de tasas de crecimiento y asíntotas, permitiendo que más de un parámetro del modelo dependa de la calidad de sitio, haciendo más flexibles las curvas polimórficas con múltiples asíntotas. Así mismo, se corrigió la autocorrelación mediante la prueba estadística de Durbin Watson (DW). En general, para todos los sitios se obtuvieron ganancias significativas, al obtener errores menores a 1.2 m y coeficientes de determinación ajustados que explican más de 97 % de la varianza total de crecimiento en altura en función de la edad, así como valores de DW aproximados a 2 en el que rectifica los valores proporcionados por los criterios de información Akaike; lo cual es deseable para modelar datos con tendencia de crecimiento sin afectar las predicciones de índice de sitio. Las ecuaciones se recomiendan para elaborar estudios de planes de manejo de esta especie en distintos sitios para clasificar la productividad maderable.
