getCC.XBAR: get Phase I corrected charting constant

In bolus123/PH1XBAR: Phase I Shewhart X-Bar Chart

get Phase I corrected charting constant

Description

Obtain a corrected charting constant.

Usage

getCC.XBAR(
	fap0
	,m 
	,var.est = c('S', 'MR') 
	,ub.cons = 1 
	,method = c('exact', 'BA')
	,interval = c(1, 5)
	,nsim = 10000 
	,nu = m - 1 
	,lambda = 1
  	,verbose = FALSE
)

getCC(
	fap0
	,m 
	,var.est = c('S', 'MR') 
	,ub.cons = 1 
	,method = c('exact', 'BA')
	,interval = c(1, 5)
	,nsim = 10000 
	,nu = m - 1 
	,lambda = 1
  	,verbose = FALSE
)

Arguments

fap0	nominal false Alarm Probabilty in Phase 1
m	number of subgroups
var.est	'S' - use mean-square-based estimator, 'MR' - use moving-range-based estimator
ub.cons	unbiasing constant
method	'exact' - calculate results using the exact method, 'BA' - calculate results using the Bonfferoni approximation
interval	searching range of charting constants for the exact method
nsim	number of simulation for the exact method
nu	degrees of freedom for the Bonfferoni approximation
lambda	constant for the Bonfferoni approximation
verbose	print diagnostic information about fap0 and the charting constant during the simulations for the exact method

Value

Object type double. The corrected charting constant.

Examples

set.seed(12345)

# Calculate the charting constant using 10 simulations and mean-square-based estimator
getCC.XBAR(fap0=0.05, m=20, nsim=10, var.est='S', verbose = TRUE)

# Calculate the charting constant using 10 simulations and moving-range-based estimator
getCC.XBAR(fap0=0.05, m=20, nsim=10, var.est='MR', verbose = TRUE)
