This assignment focuses on Topic 3 Q1 Run our RStudio file “ch07-hotels-simple-reg_update.R” and attach output figures (note that you need to set your own setwd paths and install necessary packages). This exercise simply replicates our work during class. Q2 Analyze the pattern of association between how easy it is to do business in a country and how much income the country generates. Download the data from the World Bank on GDP per capita in PPP(y) and the time required to start a business (x) for a recent year. Estimate a non-parametric (e.g. bin scatter) and parametric (e.g. linear regression) regression, and visualize the results. You can exactly follow our steps in the hotel case.
