Linear Regression - Statistics

I can not have all the information about you, but if I know how tall you are I can predict your weight. if you tell me how old you are I can tell your preference about music. Or, if you say your education level, immediately I can figure out your monthly salary. Also, if you give a hint about the movie you like, I can easily suggest another you might like.

It can appear like magic, but it's only a simple way to say what Linear Regression means ;) 

The reason why once you have chosen new movies on NetFlix, all the new suggestions simply appear, making your life easier. 

Linear Regression studies the historical behaviors to auto determine the prediction answers and options.
