Hi Statalisters,
I have a dataset that was given to me that looks like this:
ID	TRIM	PLASMA	URINE		HS1		HS2		HS3		HS4
1	1	1
1	1			1
1	1					1
1	1							1
1	1									1
1	1											1
2	1	1
2	1			1
2	1					1
2	1							1
2	1									1
2	1											1
1	2	1
1	2			1
1	2					1
1	2							1
1	2									1
1	2											1
2	2	1
2	2			1
2	2					1
2	2							1
2	2									1
2	2											1
.	.
.	.
.	.
I tried to reshape the data to the wide form using the reshape command but cannot seem to do this because I do not have a unique value for each ID and TRIM.  I ultimately want one row for each ID and trimester:
ID	TRIM	PLASMA	URINE		HS1		HS2		HS3		HS4
1	1	1		1		1		1		1		1
1	2	1		1		1		1		1	      1
2	1	1		1		1		1		1		1
2	2	1		1		1		1		1	      1				
Any suggestions?
Kelly
