In this video, the instructor illustrates making predictions with regressions.
- [Narrator] Let's talk about a specific example…using regression analysis.…In this case, we're looking at predicting…the estimated home heating oil use…by a particular customer, based on three different factors.…A variable that we call the intercept,…the temperature outside,…and the level of insulation in the customer's house.…Let's focus on these bottom three rows in the table,…and in particular, focus on the column labeled Coefficients.…These coefficients tell us the impact…on home heating oil use…in a particular month given the temperature outside…and the insulation level of the person's house.…
Now, let's see how we would use this in a prediction.…There's three steps to the prediction,…run the regression, which I showed you the output…from the previous slide,…then we're going to save those coefficients.…That was those last three rows of data.…For example, this will help us to measure the impact…for each additional inch of insulation in a person's house.…And then, finally, we're going to use those coefficients…
