Trend аnd Seаsоnаlity Mоdeling (27 pоints) 1a. Plot the Time Series and the ACF plot for the series. Comment on the stationarity of both time series based on these plots. Which (if any) stationarity assumptions are violated for the time series? (3 pts) 1b. Fit a moving average trend, splines trend estimation and a local polynomial trend on the time series. Overlay the fitted values derived from each trend estimation model on the corresponding data and calculate the Mean Absolute Percentage Error MAPE for the fitted values from each model. Comment on the effectiveness of each model to estimate the trend for the series. (7 pts) 1c. Fit an ANOVA and a cos-sin seasonality model on the time series. Overlay the residuals of the fitted values derived from each seasonal estimation model and comment. Calculate the MAPE for the fitted values from each model. Comment on the significance of each model estimation of the season coefficients for the series. (7 pts) 1d. Fit a nonparametric trend-seasonality model to the time series. Overlay the fitted values and calculate MAPE for the model. How does the fit of this model compare with the trend estimation models that you created in 1(b) and the seasonal models created in 1(c)? Does the addition of seasonality improve the fit? (7 pts) 1e. Plot the residuals and the residual ACF and PACF for the model that you created in 1(d). Evaluate stationarity for the model residuals graphically. Provide your explanation on whether the stationarity assumptions hold. (3 pts)
Sаy yоu’re а single individuаl in 2020 whо earned $70,000. Yоu would pay 10 percent on the first $9,875 of your earnings ($988); then 12 percent on the chunk of earnings from $9,876 to $40,125 ($3,630), then 22 percent on the remaining income ($7,287.50) Your total tax bill would be $11,905.50. Divide that by your earnings of $70,000 and you get an effective tax rate of 17 percent, which is lower than the 22 percent bracket you’re in. This is an example of what tax system?
