Drawing on the term's accumulated decisions, the PHLT 8500 closing memo defends one logistic specification for night shift work and hypertension against a rival adjusting for BMI and sleep.

What a finished PHLT 8500 Week 11 final modeling memo looks like
Six to eight pages in memo form, holding a specification table, a comparison table and diagnostics in an appendix. Its first two sentences give the question and the answer. The specification section lists each term with its reason, tracing each to earlier weeks: the confounders from the causal diagram, job category defended against the classmate challenge, smoking retained from the comparison week, the age interaction reported but not carried forward. A rival section fits the alternative adjusting for BMI and sleep and shows the night shift odds ratio shrinking under it. The defense explains that the rival answers a different question, the association not operating through weight or sleep, and says when that question would be worth asking. STROBE's call for both unadjusted and adjusted estimates is followed in the results table. Limitations close it.
How a PHLT 8500 Week 11 example is structured
Its intended reader will ask why this model and not another, so the defense is built into its order. Question and answer come first. The specification follows, with every term's reason stated and dated to the week it was decided, which shows the model was assembled deliberately. Results are presented with unadjusted and adjusted estimates side by side. The rival comes next and is presented at its strongest, with its own table and a fair account of what it estimates. The defense section argues from the estimand: because the question concerns the total association of shift work, adjusting for variables it plausibly causes would answer something narrower. A sensitivity paragraph shows how conclusions change under the rival. Limitations address measurement, residual confounding and the cohort's single employer. The appendix holds diagnostics.
Every term, with its week
The specification table lists each term, its form, its reason and the week the decision was made. A reader tracing any term back finds the argument that put it there, which is what distinguishes a built model from a found one.
Unadjusted and adjusted, side by side
Following STROBE's call for both, the results table shows the crude and the adjusted night shift odds ratio with intervals, so a reader sees exactly how much the adjustment moved the estimate.
The rival at full strength
The alternative adjusting for BMI and sleep is fitted and reported in its own table. Presenting it fairly, not as a straw model, is what gives the defense its credibility.
Different questions, not better and worse
The rival estimates the association not operating through weight and sleep. The memo argues that this is a legitimate question, just not the one posed, and names when a program designer would want it.
What would change the conclusion
A sensitivity paragraph reports the night shift estimate under both specifications and under one with an alternative age form. The memo states which conclusions hold under all three and which depend on the choice.
Where marks go in PHLT 8500 Week 11
The defense against the rival is where this memo earns or loses its standing. A memo that presents one model and mentions an alternative in passing has not defended anything, and graders mark the central criterion down accordingly. The rival must be a plausible one, presented fairly; a straw model adds nothing. The defense is judged on reasoning from the estimand, and a choice justified by fit statistics alone misses the point the term has been building. Traceability of each term to an earlier decision earns substantial credit. Reporting both unadjusted and adjusted estimates is expected. Sensitivity analysis is valued in doctoral sections. Limitations must be specific to this cohort. Memo organization, table clarity and APA formatting account for the remaining share.

Forward the final memo instructions and rubric with your earlier modeling work, or a summary of the decisions it contains. A modeling memo that traces every term, presents a fair rival and defends the choice from the question comes back in 24-48h, and nothing is owed the first time. Its cohort and estimates are composite; your memo defends your own specification.
PHLT 8500 Week 11 questions, answered
How should the rival model be chosen?
It should be the alternative a knowledgeable critic would propose, not a weak model set up to lose. Often that means adjusting for a contested variable, using a different functional form, or choosing another model family. The memo explains why this rival is the serious one. A rival nobody would defend makes the chosen specification look arbitrary rather than tested.
Should the memo report every model fitted during the term?
No. It reports the final specification, the rival, and any alternatives that changed a decision, with a sentence each. Exploratory models that led nowhere can be summarized in the appendix or omitted. The test is whether the path from question to specification stays visible without wading through every attempt made along the way.
What does STROBE require for a memo like this?
STROBE is a checklist for reporting observational studies rather than a requirement of this course, but many sections expect its logic: describe the cohort, define variables, explain how confounders were chosen, and report unadjusted and adjusted estimates with their precision. Following it signals that the memo meets the standard a journal reviewer would apply, and it keeps important details from being left out.
