    The evaluation of timber resources of the wood has been indispensable for the development of management and forest use programs. For this reason, volumetric estimation of timber stocks has been a common practice for forest managers. The techniques and methodologies applied for this practice are very expensive and time-consuming. For this reason, alternative techniques have been sought that are more accurate and require less time for execution. This has been done through the implementation of statistic models and computer systems. This paper describes the creation and implementation of a computer program that validates 12 statistical models widely used in the construction of volumetric tables of species of pine timber in cold temperate climates. The program allowed selection of the model that best fits for the variables normal diameter and total height: the Modified Meyer model with Intercepted Origin (MMIO), which had the best fit for the variables normal diameter and total height with a coefficient of determination (R2) of 0.983 and a high correlation coefficient, as well as a mean square error of 0.0077. Finally, the program generates the table of timber volumes, using the mathematical model that is more precise in the calculation of the volume of the stand.
