Another equality topic addressed in the OECD’s gender studies is the pay gap. Using pay gap data in the data file OECD Pay Gap Data, develop a first-order and second-order autoregressive model for the pay gap in Australia. Use the data from 1975 through 2013 to build your autoregressive model. Next, forecast pay gap values for the years 2014 to 2018. Discuss the differences in the accuracy of the forecasts compared to the actual results, compare the performance of firstand second-order models, and indicate the reasons for these differences.
