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 randomized population flag (RANDFL) onto a subject
listing.
Input: a Parquet export from the randomization system with one record
per subject, in which RANDFL is stored as a true-or-false (Boolean) value
rather than as text.
Variables:
RANDFLwould beYfor a subject in the randomized population, taken from the export.
A true-or-false value is none of the kinds of value a study column holds:
text, a whole number, a number, a date or a date and time. Reading it as
text, as true or 1, or as a number would each be a choice the study
never made, and none of them is the Y the flag takes. The run is rejected
while the export is read, and no artifact is accepted.
How to fix
Have the randomization system export the flag the way the study defines it:
the text Y for a randomized subject and an empty value for one who was not.
The study does not need to change.
