dataAlignment: Alignment of the data

In SNSchart: Sequential Normal Scores in Statistical Process Management

Description

Align the monitoring sample X and the reference sample Y.

Usage

dataAlignment(
  X,
  Y,
  alignment = "unadjusted",
  constant = NULL,
  absolute = FALSE
)

Arguments

X	vector. Monitoring sample.
Y	vector. Reference sample.
alignment	character string. Aligment of the data X and Y. Select from "unadjusted": nothing is sustracte from X and Y (default). "overallmean": overall mean is sustracted from X and Y. "overallmedian": overall median is sustracted from X and Y. "samplemean": mean from corresponding group (X and Y) is sustracted from its corresponing vector. "samplemedian": median from corresponding group (X and Y) is sustracted from its corresponing vector. "referencemean": mean from Y is subtracted from X and Y. "referencemedian": median from Y is subtracted from X and Y. "constantvalue": a constant value is subtracted from X and Y.
constant	scalar. Only used when the alignment is selected "constantvalue". Default NULL.
absolute	logical. If TRUE, the absolute aligned values are obtained. (Default FALSE)

Value

Multiple output. Select by output$

• X: vector. Monitor sample with the alignment selected.

• Y: vector. Reference sample with the alignment selected.

Examples

X = c(30, 45, 50)
Y = c(20, 22, 25, 30, 70)
dataAlignment(X,Y)
