COVID cаses mаy interest ecоnоmists аs they relate tо the economy as a whole or they may be of interest to health economists in their own right. The data set here contains data obtained from the CDC on COVID 19 cases in Maricopa County Arizona. The two variables of interest are the date and the Weekly_Cases which is the weekly number of COVID cases. More details on the data source are in the key which will be available after the exam closes. As you will see looking at the dates, the time series runs from June to December 2022. a) Plot the weekly cases. T/F: there is a general trend in which the cases are rising over the time period of the data. [a_false]. b) Check the five number summary for the weekly cases. What is the median number of cases? [b_7152]. c) Create a lag of weekly cases. Regress weekly cases on its lag. Report the R squared for this regression. [c_pt851]. d) Is the estimated coefficient on the lagged number of cases statistically significant at the 0.05 level or better? [d_yes]. e) Examine the default residual plots in R. Based on these plots, are there any influential observations? [e_NO]. f) Conduct a test for autocorrelation which we have used in the class. Based on the results of this test you conclude the errors are [f_notcorrelated]. g) If the errors are correlated use the Cochrane-Orcutt procedure to repeat the regression from part (c). What is the estimated coefficient on the lagged number of cases? [g_notcorrelated]. h) Examine the plot from part (a). Confirm the plot suggests a change in the trend which begins just after what is fall break at ASU and what is either Columbus Day or Indigenous Peoples' Day or First People's Day; these holidays are around October 12th. Create an indicator variable which equals 1 beginning with October 12 and is 0 before that date and then use the indicator to create an interaction term with the lagged number of cases. Regress the weekly cases on the lagged value and the interaction term. Caution: there are two explanatory variables in your regression but depending on how you incorporate it R may assume you want to include the indicator variable as well. Be sure to create a new variable for the interaction and check your regression output to verify that the indicator variable is not present in the model. Using this model, where the independent variables are the lag and the interaction, is the interaction term statistically significant at the 0.05 level or better? [h_no]. i) For dates after October 12th you can use your model to formulate an equation
Akаike's Infоrmаtiоn Criteriоn is а statistic that statisticians and econometricians sometimes use for variable selection during model building.
