Betreff: st: Help with filling in dates in a dataset
Hi Statalisters,
I have a reasonably simple query and have searched the help and archives
without identifying a solution.
I have count data recorded on different dates over a year. The dataset only
contains records for dates where there were observations. I want to fill in
the series, so I have a dataset that has 0 counts for days with no
obersvations. An example of what I currently have and what I want to end up
with are below.
Current Dataset:
Date Hospitalisations Deaths
1 Jan 08 1 0
3 Jan 08 3 0
5 Jan 08 0 1
7 Jan 08 0 1
8 Jan 08 1 0
11 Jan 08 2 1
12 Jan 08 3 0
14 Jan 08 1 0
Desired Dataset:
Date Hospitalisations Deaths
1 Jan 08 1 0
2 Jan 08 0 0
3 Jan 08 3 0
4 Jan 08 0 0
5 Jan 08 0 1
6 Jan 08 0 0
7 Jan 08 0 1
8 Jan 08 1 0
9 Jan 08 0 0
10 Jan 08 0 0
11 Jan 08 2 1
12 Jan 08 3 0
13 Jan 08 0 0
14 Jan 08 1 0
Is there a simple way of generating these extra records with zero counts?
All help gratefully received.
