yamaa As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.
We suggest spending no more than 5 minutes on a review. The other tabs beside Your review are background for assessment, not under review.
Summary
EditUnder reviewWhat this benchmark meansREADME.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: build SMOKEFL from collected smoking status, matching
without regard to case.
Input: collected demographics carrying reported smoking status
(SMOKSTAT).
Variables:
SMOKEFLwould be the smoking flag taken fromSMOKSTATwithout regard to case:YgivesY,ygivesY, andNgivesN. The entries forYandycollide on the keyYonce case is ignored, so the run is rejected before any data is read and no artifact is accepted.
How to fix
For case-insensitive matching, retain only one dictionary entry for each
folded key. Both Y and y then resolve through Y:
mapping:
source: DM.SMOKSTAT
case_sensitive: false
dict:
Y: "Y"
N: "N"
Alternatively, set case sensitivity on when differently cased values are intentionally distinct and give each one an explicit meaning.
