Review ask

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

Lifecycle: reviewedEditUnder review
What this benchmark means
README.md

Public entries: Python and R. Passing coverage requires an installed inventory.

Goal: attempt the total of each subject's collected results (AVALTOT), written as the row formula SUM(AVAL).

Input: laboratory (LB) records carrying the study and subject identifiers, the test code (LBTESTCD) used for the parameter code, and the collected numeric result (LBSTRESN).

Variables:

  • AVAL would be the collected numeric result from LBSTRESN; missing when the collected result is missing.
  • AVALTOT would be the total of AVAL across the subject's records, repeated on each record for that subject.

SUM(AVAL) is written as a row formula, but a row formula sees one record at a time and cannot reach the other records it would have to total, so the run is rejected before any data is read and no artifact is accepted.

How to fix

Use an aggregate and state the subject-level keys explicitly:

derivation:
  aggregate:
    group_by: [STUDYID, USUBJID]
    expr: "SUM(AVAL)"

The total is then broadcast to each parameter row for that subject.
