Summary

A linear model is a very powerful tool that you can use as an initial learning algorithm if your data matches its assumptions. Understanding linear models will help you to understand more sophisticated models that use linear models as building blocks.

Next up, we will continue using the Titanic example by addressing model complexity and assessment in more detail. Model complexity is a very powerful tool and you need to use it carefully in order to enhance the generalization error. Misunderstanding it will lead to overfitting problems.
