We are going to use the adult dataset from UCI, which focuses on census data with a view to identifying if adults earn above or below fifty thousand dollars a year. The idea is that we can build a model from observations of adult behavior, to see if the individuals earn above or below fifty thousand dollars a year.
Multiple regression builds a model of the data, which is used to make predictions. Multiple regression is a scoring model, which makes a summary. It predicts a value between 0 and 1, which means that it is good for predicting probabilities.
It's possible to imagine multiple regression as modeling the behavior of a coin being tossed in the air. How will the coin land—heads or tails? It is not dependent on just one thing. The reality is that the result will depend...
