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: carry the site name (SITENM) onto a subject listing.
Input: collected demographics carrying SITENM.
Variables:
SITENMwould be the name of the site the subject enrolled at, taken from the collected value.
One stored site name holds a byte written in an older encoding, which is not valid UTF-8 text. Replacing the byte with a substitute character would store a name the study never recorded, and dropping it would store a different name again, so the run is rejected while the file is read and no artifact is accepted.
How to fix
Export the listing as UTF-8, so every collected character keeps the value it
was entered with. The second site name then stores its accented letter (o
with circumflex, U+00F4) as the two bytes C3 B4 instead of the single byte
F4 that the older encoding wrote.
Converting a file after the fact is safe only while the original encoding is known. A study that stores names in an unstated encoding cannot say which letters it collected.
