## Question

How to compute the time window in model deployment?

Every time I input the code for the problem I get NA. Am I doing something wrong and is there some other dataset I am supposed to be using?

I understand this by hand but don't know if I am missing something.

Thanks for helping.

** Answer or follow-up question 1** Hi Nicola,

You don't need to use a dataset. If you need to use data if will be mentioned in the question.

Yes you can solve it by hand. If you do it in R (and hence show your approach) you can get partial credit if your answer is not 100%

correct.
