Glossary of statistical data
I-MR Chart
- Individual Value = Control Chart
- Moving range = interval between 2 values
Capability indices
| Cp | Potential level of performance that your process obtain, if all special causes were eliminated. ( > 1,33) |
Pp | Actual capability of your process, or how your process is actually performing relative to the specification limits. (> 1,33) | |
| CPL | Measures how close the process mean is running to the lower specification limit. | |
| CPU | Measures how close the process mean is running to the upper specification limit. | |
| Cpk | Equals the lesser of CPU and CPL. |
Probability Plot
| Points | Estimated percentiles for corresponding probabilities of an ordered data set. |
Middle lines | The expected percentile from the distribution based on maximum likelihood parameter estimates. If the distribution is a good fit for the data, the points are close to the middle line. | |
Left lines and right lines | Formed by connecting the lower bounds of the confidence intervals for the percentiles. Similarly, the right line is formed by connecting the upper bounds of the confidence intervals for the percentiles. If a distribution is a good fit, the points fall within these bounds. | |
Anderson-Darling test statistics with corresponding p-values | Use to assess whether your data follow the specified distribution. |
