  3. Inference for Linear Regression in R

Exercise

LA Homes, multicollinearity (1)

In the next series of exercises, you will investigate how to interpret the sign (positive or negative) of the slope coefficient as well as the significance of the variables (p-value). You will continue to use the log transformed variables so that the technical conditions hold, but you will not be concerned here with the value of the coefficient.

Instructions

100 XP
  • Run a linear regression on log price versus log sqft for the LAhomes dataset, then tidy the output.
  • Look at the output. Is the relationship is positive or negative? Is relationship is significant?
