ResumoLight Detection And Ranging (LiDAR) is an active remote sensor that has been successfully applied for characterizing canopy structure, especially to estimate aboveground biomass (AGB). Parametric models, mainly the linear regression with stepwise feature selection (LMstep), are the most common approaches used for estimating AGB. However, non-parametric machine learning techniques, such as Support Vector Regression (SVR), Stochastic Gradient Boosting (SGB), and Random Forest (RF), can better address complex relationships between biomass and remote sensing variables. Therefore, it is desirable to assess the performance of different regression strategies. This study aims to compare eight regression techniques for LiDAR-based AGB estimation: LMstep, Linear Models with Regularization (LMR), Partial Least Squares (PLS), K-Nearest Neighbor (KNN), SVR, RF, SGB, and Cubist. For this purpose, 34 LiDAR metrics were regressed against AGB from 147 inventory plots across the Brazilian Amazon Biome. Models performance were evaluated by the average Root Mean Squared Error (RMSE) and R2 from a 5-fold cross-validation strategy with 10 repetitions. The Kruskal-Wallis test was used to evaluate statistical differences among models. Results showed that LMstep presented the highest RMSE (68.85 Mg.ha-1) and lowest R2 (0.66), while SVR had the lowest RMSE (65.23 Mg.ha-1) and highest R2 (0.69). However, the differences in performance of the models were not statistically significant. Thus, we confirmed the results of previous studies that showed that simple approaches, such as linear regression models, performed just as well as advanced machine learning methods for estimating AGB based on LiDAR data.
