Multivariate control chart for qualitative variables

Description

Multivariate control chart T2 Hotelling applicable for qualitative variables.

Usage

T2_qualitative(base, IndK, dim, interactive = FALSE, alpha = 0.0027)

Arguments

base	Data set
IndK	Character with the name of the column that specifies the partition of the data set in k tables.
dim	Dimension taken for reduction. Initial dimension - 1 is recommended.
interactive	If it is TRUE, the graph will be shown interactively. If FALSE, the graph is displayed flat. FALSE is the default.
alpha	Type I error, it is recommended to reach this value by using the ARL.

Value

A control chart made with the T2 hotelling statistic, applied to detect anomalies in any of the K tables obtained with the specification of IndK. The control limit of the graph is obtained from the number of dimensions dim and the type I error alpha.

Examples

data(Datak10Contaminated)
T2_qualitative(Datak10Contaminated,"GroupLetter",9, FALSE,0.0027)
