- What specific conclusion is made if the H0 of the parallel lines test is rejected?
- What R function is used to perform multiple comparisons for slopes? What are its arguments?
- How does the results in the
$contrastsand$emtrendsportions of results fromemtrends()differ (i.e., what is shown in each portion)? - What specific conclusion is made if the H0 of the coincident lines test is rejected?
- What R function is used to perform multiple comparisons for intercepts? What are its arguments?
- How does the results in the
$contrastsand$emmeansportions of results fromemmeans()differ (i.e., what is shown in each portion)? - What specifically is shown in under
emmeansin the$emmeansportion of the results foremmeans()? How can you change this?
- [Optional] What questions do you have from this reading that you would like me to address? [Please be as specific as possible. Don't just say "everything" or "I don't understand anything." Of course, you can ask me questions about the reading before class on MS Teams.]
