LA Homes, multicollinearity (3)
Now, regress the log transformed variable price on the log transformed variables sqft AND bath. The model is a three dimensional linear regression model where you are predicting price as a plane (think of a piece of paper) above the axes including both sqft and bath.

- Run a
tidylmon the log transformed variablespriceand both ofsqftandbathfrom the datasetLAhomes. Use the formula:log(price) ~ log(sqft) + log(bath). - Now look at the coefficients separately. What happened to the signs of each of the coefficients? What happened to the significance of each of the coefficients?
