In bolus123/PH2XBAR: Phase II Shewhart X-bar Chart

Description

Build a Phase II Shewhart X-bar control chart.

Usage

PH2XBAR(
   X2,
  X1,
  cc = NULL,
  ARL0 = 370,
  interval = c(1, 4),
  CUC.tol = 1e-2,
  CUC.maxIter = 1000,
  EPC.p0 = 0.05,
  EPC.epstilda = 0,
  cc.option = c('EPC', 'CUC'),
  apprx = FALSE,
  ubCons.option = TRUE,
  plot.option = TRUE)

Arguments

X2	Phase II sample
X1	Phase I sample
cc	given charting constant. If cc = NULL, it will be calculated using the CUC and EPC methods.
ARL0	the nominal value of average run length
interval	the searching range of charting constants. The default setting is between 1 and 4.
CUC.tol	tolerance level for the expectation of the conditional average run length for the CUC method. The default setting is 1e-2.
CUC.maxIter	maximum iteration of computation for the CUC method. The default setting is 1000.
EPC.p0	the nominal value of probability for the EPC method. It is not recommended using values greater than 0.5. The default setting is 0.05
EPC.epstilda	the nominal value of tolerance factor for the EPC method. The default setting is 0.
cc.option	the computational option for the charting constant. The default setting is both the CUC and EPC methods.
apprx	the approximation method option. For the default setting, the approximation method does not involve.
ubCons.option	the unbiasing constant option. For the default setting, the unbiasing constant is invovlved and c4 is applied.
plot.option	the plot option. The default setting is to graph the Phase II control chart.

Examples

# Build a Phase II basic Shewhart control chart

data(Ph1data)
data(Ph2data)

X1 <- as.matrix(Ph1data[, 2:4]) ^ (1/3)
X2 <- as.matrix(Ph2data[, 2:4]) ^ (1/3)
X2[which(is.na(X2))] <- mean(X1)

PH2XBAR(
  X2 = X2,
  X1 = X1,
  cc = NULL,
  ARL0 = 370,
  interval = c(1, 4),
  CUC.tol = 1e-2,
  CUC.maxIter = 1000,
  EPC.p0 = 0.05,
  EPC.epstilda = 0,
  cc.option = c('EPC', 'CUC'),
  ubCons.option = TRUE,
  apprx = TRUE,
  plot.option = TRUE)
