1. Consider the time series data mdeaths available in R. (a) Decompose the series into trend, seasonal effect, and residuals using an additive model. Save the residuals in ResidualAll. Which observations in Residual All are not available? Why are they not available? (b) Save all available residuals in Residual. Plot the correlogram for Residual. Compute the upper confidence limit and the lower confidence limit shown in the correlogram as blue dashed lines.
