So, how to look at model M4? In addition to trying to interpret the parameters, you should look at the predictions the model makes. Look at the predicted Y for various combinations of X1, X2 and X3. Make graphs. What graphs you should make depends on the nature of the X variables but if all are continuous then coplots can be good.

If the simple regression for the expected price (in US$) of a diamond given its weight (in carats) is modeled as E(Price │ Weight) = -260 + 3721 ⨯ Weight , then what is the expected price of a diamond that weighs 0.2 of a carat?
3.2 Learning Objectives. After completing this week, you are expected to be able to: Differentiate between parametric and nonparametric regression.; Understand how model flexibility relates to the bias-variance tradeoff and thus model performance.; Use R packages and functions to fit KNN and decision tree models and make predictions or estimate conditional means.
Q. There is a linear relationship between the number of chirps made by the striped ground cricket and the air temperature. A least squares fit of some data collected by a biologist gives the model ŷ = 25.2 + 3.3x, 9 < x < 25, where x is the number of chirps per minute and ŷ is the estimated temperature in degrees Fahrenheit.

In regression, we can produce a statistical model that allows us to predict values of our outcome variable based on our predictor variable. This table also gives us all of the information we need to do that. This model takes the form of a statistical equation where: Y = B 0 + B 1 X 1 + B 2 X 2 • Where Y represents the outcome variable • X 1
