Document uncertainty by naming what is unknown, explaining why it matters and showing how it affects the decision. A language model's confident tone is not a measured probability that its business conclusion is correct. Asking it for a confidence percentage does not create a calibrated estimate.

For an analyst, uncertainty can come from missing records, ambiguous definitions, sampling variation, model assumptions or unsupported interpretation. These sources need different treatment.

Start with the uncertainty actually present

Consider the original retail availability example: eight expected product-day snapshots, six known availability states, two confirmed out-of-stock snapshots and two unknown states. The rate among known observations is two divided by six, or approximately 33.3%.

That is not automatically the rate across all eight expected snapshots. If both unknown states were in stock, the full-grid rate would be 25%. If both were out of stock, it would be 50%. The evidence identifies a range under those two endpoint assumptions.

These are missing-data bounds, not a statistical confidence interval. They do not describe stockout duration, lost sales or a forecast of future availability.

Calculate the bounds before writing the paragraph

python
from fractions import Fraction

expected,known,out,unknown = 8,6,2,2
assert known+unknown==expected
observed_rate = Fraction(out,known)
lower = Fraction(out,expected)
upper = Fraction(out+unknown,expected)
coverage = Fraction(known,expected)
assert observed_rate==Fraction(1,3)
assert (lower,upper,coverage)==(Fraction(1,4),Fraction(1,2),Fraction(3,4))
threshold = Fraction(3,10)  # Fictional decision threshold for this exercise.
assert lower<=threshold<upper
print({'known_snapshot_rate_percent':float(observed_rate)*100,
       'full_grid_bounds_percent':[float(lower)*100,float(upper)*100],
       'coverage_percent':float(coverage)*100,
       'threshold_classification':'not_identified_from_available_states'})

At the fictional 30% threshold, the possible full-grid rate falls on both sides. The available states do not establish which classification is correct. This is more decision-relevant than writing “the model is moderately confident.”

The full source and validation workflow are available in the retail availability capstone. The numbers above are a compact restatement of its synthetic example.

Write a narrative that separates facts and consequences

A suitable paragraph is: “Two of six known snapshots were out of stock. Availability is known for six of eight expected snapshots. Across the full grid, the out-of-stock share could range from 25% to 50%, depending on the two unknown states. Resolve those states before classifying performance against the 30% threshold.”

This paragraph supplies the numerator, denominator, coverage and decision consequence. It does not claim a probability for either endpoint or assume the missing states resemble the observed ones.

If the unknown states cannot be recovered, state the assumption required for any point estimate. For example, using the observed rate for all snapshots assumes an appropriate relationship between observed and missing states. That assumption is not established merely because the assistant writes it fluently.

Keep other uncertainty types distinct

Sampling uncertainty concerns what a sample tells us about a broader population under a sampling model. A confidence interval requires the relevant design and assumptions; it is not interchangeable with the missing-state bounds above.

Predictive uncertainty concerns a model's future outcomes and should be evaluated using suitable held-out data and calibration checks. Language-model uncertainty about wording or factual support is another issue. A self-reported “90% confident” answer has no demonstrated calibration in this lab.

Definition uncertainty arises when a business term is unresolved. If “revenue” could mean orders, recognized revenue or cash collection, clarify the measure before attaching a range to an unspecified quantity.

Make uncertainty actionable

Name the smallest additional evidence that would change the decision. Here it is the missing availability state for each of two product-day cells. In a causal claim, it may be a credible comparison design; in a financial measure, it may be dated ledger entries.

Exercise: assume one unknown state is confirmed in stock. Recalculate the bounds and explain whether the 30% threshold becomes decidable. Preserve the original eight-cell denominator.
