Can you figure out if any R functions used to subset a time series 1 or more below? 1. subset () 2. head () 3. rwf () 4. tail () 5. holt () 6. tail () what could fit
Homework Answers
The functions such as subset(), head() and
tail() are there for subsetting the time series.
This can help us to subset the few elements of the head of the list
or the elements from the back of the list.
And the functions rwf() and holt() can
fit.
the above functions can fit on the linear or random data.
That was a nice
question to answer
Friend, If you have any doubts in understanding do let me know in
the comment section. I will be happy to help you further.
Thanks
