Appendix — Accounting refresher map (from the PDF)
Track D is a statistics + forecasting track. But we deliberately keep an bookkeeping refresher running in the background so learners always remember why the analysis matters.
The original 4-page PDF motivating Track D clusters the “accounting foundations” into:
Bookkeeping basics (measurement, ethics, double-entry, GL, statements)
Assets (inventory control, depreciation, property)
Liabilities & equity (AP/debt, payroll/tax, equity types)
Financial statement analysis (bank rec, metrics for decisions)
How we guarantee coverage
Every Track D chapter includes an Accounting Connection section that:
names exactly which of the four pillars gets refreshed in the chapter, and
points to the specific dataset table(s) used (LedgerLab core and/or the NSO v1 running case).
In the textbook, this becomes a one-paragraph “coverage map” per chapter.
Where to find the first refresher
Chapter 1 (Ch 01 — Accounting as a measurement system) refreshes pillar #1 and introduces the LedgerLab core dataset.
Starting in later chapters, Track D’s default running case becomes North Shore Outfitters (NSO v1)
written to data/synthetic/nso_v1.
Later chapters (planned)
Assets refresher occurs naturally when we forecast inventory and analyze COGS.
Liabilities/payroll refreshers are taught as accrual timing + cash flow impact.
Financial statement analysis refreshers anchor forecasting outputs to decisions.
