WebJun 20, 2012 · The empirical c-statistic of the multivariable model was 0.853. The corresponding predicted c-statistics were 0.849 and 0.855 when formulas (1) and (2) were used, respectively. The improved accuracy of prediction of the c-statistic for the multivariable model is likely due to the distribution of the linear predictor having a distribution that ...
WebStatistics Process Capability (Cp) Process Performance (Pp) - Process capability can be defined as a measurable property of a process relative to its specification.
