We are interested in the relationship between annual health insurance premiums paid with yearly income from wage and salary using the following models. Model 1 : Y i=b 0 b 1 Xi ei Model 2: Y i=b 0 b 1 logXi ei Model 3: log Y i=b 0 b 1 Xi ei Model 4: logY i=b 0 b 1 log X i ei where Yi = the annual health insurance premiums (phipval) Xi = the annual income from wage and salary (incp_wag). How do I create these models
