1-Plot your X variables (Stats>Time Series>TS plot) and describe what you see. For each X variable, explain if it is stationary vs nonstationary, multiplicative vs. additive, seasonal or not, trending vs. not, if trending, is the trend linear vs non-linear?

I have already plotted the X Variable time series plots. My X variables are Personal Consumption Expenditure and the Natural Rate of Unemployment. Thanks in advance!
