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 identifier (SITEID) onto a subject listing.
Input: collected demographics stored as a Parquet file, carrying
SITEID.
Variables:
SITEIDwould be the site the subject enrolled at, as collected.
The study states that the input starts with a byte-order mark, the invisible character U+FEFF that some programs write before UTF-8 comma-separated text. A Parquet file is not text and never starts with one, so the statement cannot hold, and the run is rejected before any data is read.
How to fix
Stop stating a byte-order mark on the Parquet input; Parquet stores its text in one fixed encoding of its own:
input:
DM: input/dm.parquet
If the study meant to read a comma-separated export of the same data, name that file instead, and state the mark only when the export starts with one.
