Homeworks
- In your interpretations, please make it as easy as possible for your audience
- For example: “-0.3 lower” Is that 0.3 lower? or 0.3 higher?
- Stick to the magnitude and use lower or higher to indicate the sign!
- If the question asks for a population model, there should be NO hats!
- HW3, question 3
- Part b
- Asked for population (not estimated) model
- Part g
- Age OR fitted values can be on the x-axis
- Residuals must be on the y-axis
- Part q
- I would use the log-transformation
- The qq-plot looks much better! The residual plot looks better! The linearity looks better
- All three of these are closer to the ideal look
Labs
- Look at your html before turning it in!!
- Do not print an entire dataset! You shouldn’t need to scroll through 100,000’s of rows of data!
- If you are working with gender identity, multi-selection race, or BMI
- Please make sure you are using these variables correctly.
- Ideally, come to office hours and make sure you have the variables correct
- Points will be taken off your final project if these variables are incorrect
- Make sure your factored variables are correct!
- We should NOT see numbers on plots if the variable is categorical
- Make sure you selected variables before using
drop_NA()
