http://www.datasciencelovers.com/machine-learning/linear-regression/ WebbThe model provides us with a predicted probability that each individual will have a heart attack; if this is greater than 0.5, then that means that the model predicts that the individual is more likely than not to have a heart attack. We can start by simply comparing those predictions to the actual outcomes.
