As a clinical trial statistician or programmer, answer three short questions in Your review: the task, the inputs and outputs, and the AI-assisted review. Agreeing with all three approves this benchmark; disagreeing with any 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
README.mdPublic entries: Python and R. Passing coverage requires an installed inventory.
Goal: add the subject's mean result (AVALMEAN) for each
laboratory parameter to every collected record.
Input: collected laboratory (LB) records carrying study, subject, sequence number, test code, and the collected numeric result.
Variables:
AVAL: the collected numeric result for the record; empty when no usable result was collected.AVALMEAN: the mean of the subject's non-missingAVALvalues for the parameter, repeated on every record for that subject and parameter, including a record whose ownAVALis empty; empty, never zero, when the subject has no non-missingAVALfor the parameter.
Note: the mean is taken separately for each test code, so each of a subject's records carries the mean for its own test.

Edit16 linesFollowing CDISC ADaM standards, use the provided LB dataset to create an ADLB dataset with one record per collected laboratory record.
The output dataset should contain the following columns in this order: STUDYID, USUBJID, LBSEQ, PARAMCD, AVAL, AVALMEAN
PARAMCD is the record's collected test code. AVAL is the collected numeric result for the record, and has no value when no usable result was collected. AVALMEAN is the mean of the subject's non-missing AVAL values for the record's parameter, and the same mean is repeated on every record for that subject and parameter, including a record whose own AVAL has no value. When the subject has no non-missing AVAL for the parameter, AVALMEAN has no value; it is never zero. AVALMEAN is not rounded.
