What is linear regression?

 

In statistics, linear regression is a linear approach to modeling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).

- wikipedia

Let's try that in python

What is Train/Test set?

Training Dataset
The sample of data used to fit the model.

Test Dataset
The sample of data used to provide an unbiased evaluation of a final model fit on the training dataset.

Validation Dataset
The sample of data used to provide an unbiased evaluation of a model fit on the training dataset while tuning model hyperparameters. The evaluation becomes more biased as skill on the validation dataset is incorporated into the model configuration.
