To find out the non missing values of any particular variable at any particular position with conditional statement like it should be greater than or less than
SUB VISIT SBP DBP WEIGHT
001 1 124 134 180
002 2 170
003 3 178
004 4 345 128 150
005 5 137 167 180
006 1 136 156 178
007 2 145 152 187
008 3 187
1. Get only latest non-missing values from on or before 3 visit into 3 different data sets for DBP, SBP and Weight variables
2. Merge all three, SBP, DBP, WEIGHT
I appreciate if you guide me.
Thanks.
Your question lacks sufficient details but I will show you what I think you want. Also, the values of SUB in your example don't look right and I changed them.
