In the field of biomedical signal processing (e.g. pathological speech signal processing), often it is necessary to use binary regression analysis. For this purpose, the researchers nowadays use multiple sophisticated regression techniques and metrics to evaluate regression models. Regression grid search tool (RGST) provides an easy and fast way to optimize selected regression model.
Software RAT provides 5 possible regression techniques: Classification and Regression Trees (CART), Ordinal Regression (OR), Linear Regression (LR), Support Vector Machines Regression (SVMR), Gaussian Process Regression (GPR). It also provides 10 metrics for evaluating quality of regression process: Gini Index (GI), Absolute Error (AE), Mean Absolute Error (MAE), Squared Error (SE), Mean Squared Error (MSE), etc.
The package also provides the function for errorgraph-based visualization of the optimization process. The RGST software is written in the MATLAB programming environment. The testing scripts can be used to test functionality of the software
