Describe linear regression in terms of the relationship between variables. As you respond to earlier posts, try to add new material to the discussion such as correlation, determination, causal, risk, std dev, etc.

Solution

Linear regression is a process to model the relationship between two variables say x and y. One primary assumption is that those two variables are related , more specifically one is dependent on another, based on some pre-assumed model (linear one) we try to guess the relationship of x and y. we are given numerical data to verify & estimate our model.
