10. Time Series Analysis Plot time series for all of the variables (variable 1, 2, 3) Check and evaluate auto correlation and partial autocorrelation function for all of the variables (variable 1, 2, 3). Explain the results. Draw five-point moving average for variable 1 and show the moving average with red colour. Check seasonality with cycles (sin, cos) and evaluate regression result. Check residuals to look for patterns after you run the regression for seasonality. Explain the results.
