I could balance equations in chemistry and do some algebra and trigonometry at GCSE level. But this blows my mind. Higher tier GCSE Maths. I should have paid more attention. I think I know of what regression is in a simpistic term. It's like taking a rolling graph and predicting the next point on the x / y axis, using the previous data as a training model. I hope.

You’re exactly right. It’s fitting a higher-dimensional line or curve to the data.
