Missing Data The freetrade data frame from the Amelia package has economic and political data on nine developing countries in Asia from 1980 to 1999. The 9 variables include year, country, average tariff rates, Polity IV score, total population, gross domestic product per capita, gross international reserves, a "dummy variable for if the country had signed an IMF agreement in that year, a measure of financial openness, and a measure of US hegemony. Unfortunately, this data has missing values. (a) Explore the "missingness" in the freetrade using your choice of methods, e.g. from packages VIM mice, Amelia, and/or others. (b) Implement your own statistical test (e.g. ANOVA, t-test, chi-square, etc.) to determine if the miss ingness in the tariff variable is independent with the country variable. Does your answer change if you remove Nepal or if you remove the Philippines? Discuss why. (Note: a short description of using the chi-square goodness of fit test is available in the course website.)
