XBarSChartResult
data class XBarSChartResult(val centerLine: Double, val ucl: Double, val lcl: Double, val sChart: ControlChartLimits)(source)
Results of an x-bar and S (standard deviation) control chart analysis.
The top-level properties (centerLine, ucl, lcl) describe the x-bar chart, which monitors the process mean. The nested sChart describes the S chart, which monitors the within-subgroup variability using the sample standard deviation.
The S chart is generally preferred over the R chart for subgroup sizes above 10, because the standard deviation uses all observations while the range uses only the extremes.
