-# treeBiomass-from-allometry
 A python program was developed, which integrated a comprehensive set of allometric equations for above-ground biomass calculating at a single tree level. 
 
 The empirical allometric equations using DBH and H as predictors. There are totally 10 equations were integrated into the program, these are most frequently used equations in previous studies.

 # Method
 The main idea of the program is to use provided information of tree diameter (DBH), tree height (H), and tree biomass (AGB) apply into predefined equations to generate a set of equation parameters that best fit the data. From determined parameters, the biomass value will be predicted. The predicted biomass and the actual biomass then will be compared by visualization and accuracy assessment.

 ## Accuracy 
 All models will be fit to data and the following goodness-of-fit measures will be provided for user’s assessment: coefficient of determination (R2), Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root mean squared error (RMSE).
