Domain-specific

• C-chart
  • Under the conventional Poisson model, the in-control center is the mean count \(\bar c\), and three-sigma limits are commonly \(\bar c \pm 3\sqrt{\bar c}\), with a negative lower limit truncated to zero.
  • If exposure varies, normalizing counts by opportunity and using a U-chart is the constitutive change.
• Inferential Error
  • Listed in the references but not attached to a specific claim.
• Np-chart
  • The chart does not estimate product quality from one point; it organizes a time-ordered sequence to detect evidence that the process distribution has changed.
• Risk Score
  • Listed in the references but not attached to a specific claim.
• Statistical Test
  • Listed in the references but not attached to a specific claim.

Mechanisms

• Autocorrelation and Whiteness Test
  • Test whiteness jointly. A portmanteau statistic (Ljung–Box) aggregates many lags into one significance test; the Durbin–Watson statistic targets first-order correlation specifically.

    This sourceNational Institute of Standards and Technology. (n.d.). Defines the Ljung-Box statistic as a joint significance test aggregating residual autocorrelations across multiple lags.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 7 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
