2. What are the sources of uncertainty in a multivariate regression? How do we know how confident we should be in our regression coefficient estimates? Why might you prefer multivariate regression over other methods discussed in the course?
3. What do we mean by model fit? What measures of model fit did we discuss in this course? Discuss their definition and how to interpret them.
4. Suppose you conduct a study of randomly selected people in Spain. You ask them whether they favor increased trade with China. Approximately 55% of those surveyed state that they are in favor of increased trade with China. What would be the sample size necessary to conclude that the proportion of those in favor is significantly different from 0.5 (50% approval)? How do you know?
5. Choose a hypothesis related to international relations involving an interaction effect. Discuss how you would use multivariate regression to investigate the hypothesis. Make a regression table of hypothetical results (coefficients and standard errors) that would support the hypothesis and interpret the (hypothetical) results.
