by Vidhyadharan-ext, Vaishna
Definition
6 sigma: A sample in which each sampling unit contains a pair of observations that are not independent of one another (e.g. sampling ages of husband and wife as a single sampling unit).

Definition
MSA: It is the net effect of all significant and determinable sources of variation over time. Performances quantifies the long term assessment of combined measurement errors.

Definition
6 sigma: A capability index that measures the potential capability of a process to meet expected specification limits, or tolerance levels, in the long term, assuming the process is ideally centered (regardless of where the process is actually centered).

Definition
6 sigma: A capability index that measures the potential capability of a current process to meet expected specification limits, or tolerance levels, in the long term, using the current process average.

by Vidhyadharan-ext, Vaishna
Definition
Minitab: Indicates how well the model predicts responses for new observations, whereas R2 indicates how well the model fits your data. Predicted R2 is between 0 and 1; larger values of predicted R2 suggest models of greater predictive ability.

Definition
Minitab: Prediction sum of squares; an assessment of your model's predictive ability. PRESS, similar to the residual sum of squares, is the sum of squares of the prediction error.
P-value

by Vidhyadharan-ext, Vaishna
Definition
Minitab: The p-value is the probability of obtaining a test statistic that is at least as extreme as the actual calculated value, if the null hypothesis is true. A commonly used cut-off value for the p-value is 0.05.
