URGENT

2. You would like to investigate if democtatic voting states in the US are more affected by COVID-19 than republican voting states. You have dats for the 50 states and the District of Colombia of the following variables: - state - name of the state; - idstate - state abbreviation; - popn - estimate of population in 2019; - density - estimate of population density (in inhabitants per km2 ); - democrat - number of votes for the democratic nominee; - republican - number of votes for the republican nominee; - positive - cumulative number of positive tests; - negative - cumulative number of negative tests; - dead - cumulative number of deaths of COVID-19. - winner - winner of the state, either democrat or republican. One can consider a binomial logit model for the proportion of the number of deaths over the total nunnber of positive cases in a state. The estimated model has this proportion as a dependent variable and density and winner as independent variables. (d) Instead of using the winner variable, one can use the ratio of republican to democrat. Report the estimated parameter of this new variable and its interpretation. Test it for statistical significance. Do your conclusions change? (6 points) One can consider a negative binomial model for the mortality rate, with density and winner as independent variables, while taking into account the number of positive cases per state (as an offset).
