This Brainstorm is about the assignment you are working on this week. For that reason the due date for THIS Brainstorm is now Sunday $($instead of Thursday$)$ by midnight.

After you have completed Assignment $2,$ please briefly share your results so we can determine who has the best predictive model.

Please share the R$2,$ model $($regression equation$)$ and accuracy rate for your best model. DO NOT post the Excel file.

Accuracy rate $=($predicted price $-$ actual price$)/$actual price

What's more important, a higher R$2$ or a higher accuracy rate?

Did you make any decisions or take any actions in the Sample$-$Explore$-$Modify steps that you now regret? What and Why?
