Problem $1$

Use the series from Problem $1$ of Problem Set $3($with the same seed value as before$)$:

$```$

set.seed$(12345678)$

myseries aus$\_$retail $\%>\%$

filter$(`$Series ID$`==$ sample$($aus$\_$retail$$`$Series ID$`,1))$

$```$

Decompose the series using one of the methlods covered in class $($e$.$g$.$ X$-11,$ X$-13,$ SEATS, or STL$).$ Does it reveal any outliers, or unusual features that you had not noticed previously?
