XBarRChartResult

data class XBarRChartResult(val centerLine: Double, val ucl: Double, val lcl: Double, val rChart: ControlChartLimits)(source)

Results of an x-bar and R (range) control chart analysis.

The top-level properties (centerLine, ucl, lcl) describe the x-bar chart, which monitors the process mean. The nested rChart describes the R chart, which monitors the within-subgroup variability using the range.

XBarRChartResult

constructor(centerLine: Double, ucl: Double, lcl: Double, rChart: ControlChartLimits)

Properties

centerLine

val centerLine: Double

the grand mean (average of subgroup means) — center line of the x-bar chart.

lcl

val lcl: Double

the lower control limit of the x-bar chart, computed as grand mean minus A₂ times R-bar.

rChart

val rChart: ControlChartLimits

the control limits for the accompanying R chart.

ucl

val ucl: Double

the upper control limit of the x-bar chart, computed as grand mean plus A₂ times R-bar.

xBarChart

val xBarChart: ControlChartLimits

The x-bar chart limits as a ControlChartLimits instance for uniform handling.
