Things to take care

1. Weights and Impacts provided as arguments should be separated by comma's and equal to number of numerical columns.
2. Categorical columns are not supported yet. They should be dropped or feature engineered into numerical columns using techniques like One Hot encoding etc.
3. First column should be label column.
