Hi!
I'm trying to find the rank for the different count on values by month and year and to have first 3 positions (descending by num) for the each month. I have only one year data. Help me please to this in right way.
data have;
month=1; code='BB1111111'; year=2023; name='BB'; num=4; output;
month=1; code='AA1111111'; year=2023; name='AA'; num=8; output;
month=1; code='FF1111111'; year=2023; name='FF'; num=1; output;
month=1; code='CC1111111'; year=2023; name='CC'; num=5134; output;
month=1; code='DD1111111'; tyear=2023; name='DD'; num=525; output;
month=1; code='EE1111111'; year=2023; name='EE'; num=125; output;
month=2; code='QQ1111111'; year=2023; name='QQ'; num=4; output;
month=2; code='CC1111111'; tyear=2023; name='CC'; num=5321; output;
month=2; code='DD1111111'; year=2023; name='DD'; num=256; output;
month=2; code='WW1111111'; year=2023;name='WW'; num=151; output;
month=3; code='BB1111111'; year=2023; name='AA'; num=12; output;
month=3; code='CC1111111'; year=2023; name='CC'; num=2860; output;
month=3; code='CC1111111'; year=2023; name='DD'; num=655; output;
month=3; code='CC1111111'; year=2023; name='EE'; num=62; output;
month=4; code='AA1111111'; year=2023; name='AA'; num=2; output;
month=4; code='BB1111111'; year=2023; name='BB'; num=12; output;
month=4; code='CC1111111'; year=2023;name='CC'; num=1962; output;
month=4; code='CC1111111'; tyear=2023;name='DD'; num=865; output;
month=4; code='CC1111111'; year=2023;name='EE'; num=112; output;
run;
output I need:
month | year | code |
name |
num | rank |
1 | 2023 | CC1111111 | CC | 5134 | 1 |
1 | 2023 | DD1111111 | DD | 525 | 2 |
1 | 2023 | EE1111111 | EE | 125 | 3 |
2 | 2023 | CC1111111 | CC | 5321 | 1 |
2 | 2023 | DD1111111 | DD | 256 | 2 |
2 | 2023 | WW1111111 | WW | 151 | 3 |
etc. | ... | ... | ... | ... | ... |
You can sort the data by descending count, then take the first 3 records.
Or you can use PROC RANK and just keep the records where the rank is less than or equal to 3.
proc rank data=have descending out=want ties=low;
by month;
var num;
ranks num_ranked;
run;
Note: these two methods will not produce the same results in the case of ties.
