Help with JMP this is all the information I have; see that it contains two years of monthly data on total number of filled jobs. You are to compare three models and select the best fit one:

Model_X: Linear trend line forecasting

Model_Y: Seasonal forecasting (NOTE: season has 12 levels here, one month per season)

Model_Z: Seasonal forecasting with trend
