Unusual Grouping in SAS EG

crawfe — Fri, 10 May 2019 15:55:55 GMT

Hi. This is a somewhat off-beat question but maybe someone can help...

I am creating a small table in EG and I am coming up with more Groups than I expect.

I have X's as Category. I take Y and pull the SUBSTR first two letters (looks ok); then I use the SUMMARY COUNT

and Summary Groups=X, Y(2 letter prefix) in Query Builder.

Instead of the expected three line output table, I get a random number of rows for AA, BB, CC.

I might have multiple group rows of AA, where X and AA all look the same! What could be happening

behind the scenes to make EG think that I have multiple groups? Are there hidden attributes?

(BTW the num. of rows is not the number of AA's).

Thanks!

Input: Expected Grouped Output

X Y X Y Count Y Observed:

Grp1 AAxxdfd Grp1 AA 14 Grp1 AA 7

Grp1 AAfjroeo Grp1 BB 7 Grp1 AA 3

Grp1 AAkfirishf Grp1 CC 2 Grp1 AA 4

etc..... Grp1 BB 5

Grp1 BBdieisjd Grp1 BB 2

Grp1 BBfjruspw etc.

etc....

Grp1 CCkfiriusd

Grp1 CCforjhdhs

etc....

1. Either you have invisible characters of some kind - use COMPRESS() to try and remove them
2. You have a format applied to a group variable and SQL doesn't honour formats when doing summaries. You need to use a summary TASK instead of query builder in that case or apply the format explicitly in Query Builder.

Thanks. This got me on the right track. I used STRIP and it worked.

The Grp1's should have been from a pull-down list (no extra blanks).

Now I have to check the source. GIGO. Thanks!
