How does it measure the accuracy of a regression model?

It provides comprehensive performance metrics such as R-squared (coefficient of determination) and RMSE (Root Mean Square Error) to validate the model's reliability.

Can this skill help me predict future values?

Yes, once a model is generated and validated, you can use the skill to predict dependent variables based on new or hypothetical input data.

What types of regression models does this skill support?

The skill supports multiple regression types, including linear and polynomial models, to best fit the specific structure and complexity of your dataset.

Do I need to clean my data before using this skill?

While the skill analyzes data structure, following best practices for data cleaning and preprocessing is recommended to ensure the highest accuracy in your regression models.
