I have a dataset containing yearly and weekly data starting from week 1
1999 (i.e. week of Jan 1, 1999) to week 53. This is repeated from year
1999 to year 2004. I am trying to convert this data to monthly data,
containing the total no. of units for each month of each year. The
problem is all months (except some Februarys) contain a little more than
4 weeks, and so computing the total for each month is not
straight-forward. I guess any solution will have to include some error,
which is fine.
Any ideas? Thanks for any suggestions.
