I have two datasets 1 containing treatment/case data and the other containing potential controls. I need to match potential control to the cases but I need the output to look a certain way. I have used rangejoin and joinby but the output is not in the form I need. I have examples of the data and code and result as well as the desired result below.
TREATMENT DATASET EXAMPLE
Code:
* Example generated by -dataex-. To install: ssc install dataex clear input float(id case sex age) 1014 1 1 8 1017 1 1 10 1019 1 1 7 1019 1 1 9 1023 1 1 9 1025 1 0 6 1025 1 0 7 1025 1 1 7 1027 1 0 5 1027 1 1 10 1029 1 0 6 end
Code:
* Example generated by -dataex-. To install: ssc install dataex clear input float(id control sex age) 1014 0 1 6 1017 0 0 7 1019 0 1 7 1023 0 0 6 1027 0 0 6 1027 0 0 7 1027 0 1 8 1027 0 1 10 1029 0 0 10 1031 0 0 6 1031 0 0 10 1032 0 0 7 1032 0 0 10 1032 0 1 6 1032 0 1 7 end
Code:
rangejoin age -2 2 using"helptreat.dta", by(sex) suffix(_ctr)
Code:
* Example generated by -dataex-. To install: ssc install dataex clear input float(id control sex age id_ctr case age_ctr) 1014 0 1 6 1019 1 7 1014 0 1 6 1025 1 7 1014 0 1 6 1014 1 8 1017 0 0 7 1027 1 5 1017 0 0 7 1025 1 6 1017 0 0 7 1029 1 6 1017 0 0 7 1025 1 7 1019 0 1 7 1019 1 7 1019 0 1 7 1025 1 7 1019 0 1 7 1014 1 8 1019 0 1 7 1019 1 9 1019 0 1 7 1023 1 9 end
Code:
* Example generated by -dataex-. To install: ssc install dataex clear input float(id case_control sex age) 1014 0 0 4 1014 0 1 4 1014 0 1 6 1014 1 1 8 1017 0 0 1 1017 0 0 7 1017 1 1 10 1019 0 0 1 1019 0 1 7 1019 1 1 7 1019 1 1 9 end
Thanks
