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 the analysis start date (ASTDT) for each
collected adverse event (AE), completing a start recorded without
a day.
Input: collected adverse events carrying the reported start
(AESTDTC), which is sometimes a year and month with no day and
sometimes a year with no month.
Variables:
ASTDTwould contain the collected start, kept as collected when it is a complete date and otherwise completed with daymid(and month6for a year alone).
The day value mid is neither a day number nor one of the two
positions every month has, first and last, so the run is
rejected before any data is read and no artifact is accepted.
How to fix
Decide where in the month the analysis date should fall, then name a position a calendar fixes or name the day itself. To place a start recorded as a year and month on the first of that month:
impute:
type: date
source: AE.AESTDTC
month: 6
day: first
A value such as 2023-06 then becomes 2023-06-01. Writing day: last
instead gives 2023-06-30, and writing day: 15 names the fifteenth of the
collected month directly.
