Use the canadian$\_$gas data from the fpp$3$ package in R and perform the following tasks. Include

explanations, wherever needed.

$1.$ What type of Box$-$Cox transformation would be helpful for the data? Explain your

answer.

$2.$ Subset the canadian$\_$gas data and keep observations from March $1995$ to February

$2005.$ Plot the data using autoplot$(),$ gg$\_$subseries$(),$ and gg$\_$season$().$ Describe the

presence $($or absence$)$ of seasonality in the data.

$3.$ Perform an STL decomposition of the data. Plot the seasonal component from STL

decomposition using gg$\_$season$().$ Does the seasonal shape change over time? Explain.

$4.$ Plot a seasonally$-$adjusted series using the results from the model above. Using this plot,

explain why the seasonally$-$adjusted series is different from the original series.
