I have a dataset containing mappings of various id's used in a study.
The truly unique person identifier is the variable master. A person may
then be assigned an id:
master id1 id2 id3 id4
106 708 673 . 676
110 713 696 . 704
122 721 721 . .
123 749 722 . 728
129 789 789 734 .
134 739 739 . .
144 800 752 . 763
145 808 753 . 780
151 797 764 . 781
158 811 771 . 779
I have a working dataset containg id. The id may come from id1, id2,
id3, or id4 above:
. list id in 1/10, clean noobs
id
2014
2030
2038
2041
2042
2054
2055
2058
2061
2065
I need to merge(?) the two so that I can get the master id for each id,
regardless of whether they came from id1 id2 id3 id4.
I thought this was a job for merge, but did not find a mention for this
type of situations in the manual. I suppose I could do four sequential
merges. Any suggestion on how to best proceed?
Thanks.
