Statistical Process Control¶
← Back to Domain-Specific Abstractions by Domain
6 domain-specific abstractions whose origin domain is Statistical Process Control.
- Distribution-free control chart — A statistical process-monitoring chart whose in-control performance does not depend on a specified underlying process distribution.
- P-chart — A binomial Shewhart control chart that monitors the proportion of nonconforming units in successive samples using center and control limits adjusted for sample size.
- Regression control chart — A statistical process-control chart monitoring deviations from an expected regression relation when the process mean legitimately varies with one or more covariates.
- Shewhart individuals control chart — A paired individuals and moving-range control chart for monitoring a process one observation at a time when rational subgroups are unavailable or inappropriate.
- Tampering (quality control) — Adjustment of a stable process in response to ordinary common-cause variation, thereby increasing rather than reducing output variability.
- X-bar chart — A variables control chart that plots successive subgroup means against a center line and statistically derived limits to monitor shifts in a process mean.
