| description | Pinus durangensis is the most utilized and abundant tree species in the Guachochi region of the state of Chihuahua; however, there is a lack of appropriate knowledge to get accurate volume estimations. Therefore, the purpose of this study was to model the tapering of the bole to allow developing an equation to predict merchantable and total volume, which guarantees its operative application. For this purpose, a trigonometric model was fitted to 4 502 data pairs of 663 trees felled during harvesting operations. The goodness of fit test consisted of comparing the statistics, coefficient of determination, root mean square error, and a precision index. Model fitting includes the use of appropriate statistical procedures to account for the problems of autocorrelation and heterocedasticity associated with the development of taper equations. The model gave best results in terms of predictive capacity, and via mathematic integration, an equation for tapering was obtained which is compatible with the merchantable and the total volume. It was concluded that the generated equations have a solid statistical foundation, and therefore constitute an essential tool for improving accuracy in forestry inventories, assuring its usage not only in the study region but its application is recommended also in other sites, with the necessary adaptation of the model to the respective local conditions. |

Pinus durangensis es la especie arbórea de mayor uso y distribución en la región de Guachochi, Chihuahua, México; sin embargo, el conocimiento para estimar con veracidad su volumen es limitado, por lo cual en este trabajo se planteó modelar el ahusamiento de dicha especie que posibilite generar una ecuación de volumen comercial compatible garantizando su aplicación operativa. Con ese propósito, se ajustó un modelo trigonométrico a 4 502 pares de datos de 663 árboles derribados en operaciones de aprovechamiento forestal. La prueba de bondad de ajuste consistió en la comparación de estadísticos como el coeficiente de determinación, la raíz del error medio cuadrático y un índice de precisión. El ajuste incluyó el uso de métodos estadísticos apropiados para detectar y corregir los problemas de autocorrelación y heterocedasticidad asociados al desarrollo de ecuaciones de ahusamiento. El modelo ajustado arrojó buenos resultados en su capacidad predictiva y mediante su integración matemática se obtuvo una ecuación de ahusamiento compatible con los volúmenes comercial y total. Se concluyó que las ecuaciones generadas tienen un sustento estadístico sólido, por lo cual son una herramienta fundamental para mejorar la precisión en los inventarios forestales, asegurando así su aplicación no sólo en la región de estudio, sino que también se recomienda su puesta en práctica en otras localidades, mediante las adaptaciones a las que haya lugar.
