# XGBoostLSS - An extension of XGBoost to probabilistic modelling
We introduce a comprehensive framework that models and predicts the full conditional distribution of univariate and multivariate targets as a function of covariates. Choosing from a wide range of continuous, discrete, and mixed discrete-continuous distributions, modelling and predicting the entire conditional distribution greatly enhances the flexibility of XGBoost, as it allows to create probabilistic forecasts from which prediction intervals and quantiles of interest can be derived.

## `Features`
:white_check_mark: Estimation of all distributional parameters. <br/>
:white_check_mark: Normalizing Flows allow modelling of complex and multi-modal distributions. <br/>
:white_check_mark: Mixture-Densities can model a diverse range of data characteristics. <br/>
:white_check_mark: Multi-target regression allows modelling of multivariate responses and their dependencies. <br/>
:white_check_mark: Zero-Adjusted and Zero-Inflated Distributions for modelling excess of zeros in the data. <br/>
:white_check_mark: Automatic derivation of Gradients and Hessian of all distributional parameters using [PyTorch](https://pytorch.org/docs/stable/autograd.html). <br/>
:white_check_mark: Automated hyper-parameter search, including pruning, is done via [Optuna](https://optuna.org/). <br/>
:white_check_mark: The output of XGBoostLSS is explained using [SHapley Additive exPlanations](https://github.com/dsgibbons/shap). <br/>
:white_check_mark: XGBoostLSS provides full compatibility with all the features and functionality of XGBoost. <br/>
:white_check_mark: XGBoostLSS is available in Python. <br/>
