PTAk (version 1.2-6)

FCAmet: Tool used in Generalisation of Correspondence Analysis for k-way tables

Description

Computes the ratio Observed/Expected under complete independence with margins of the multiple contingency table (in frequencies) and gives chi2 statistic of lack of complete independence.

Usage

FCAmet(X,chi2=FALSE,E=NULL,No0margins=TRUE)

Arguments

X

a multiple contingency table (array) of order k

chi2

if TRUE prints the chi2 statistic information

E

if not NULL represent a model which would be used for an FCAk relatively to a model

No0margins

if TRUE, prevents zero margins in replacing cells involved by the min of the non-zero margins /nb of zero cells

Value

• a list with
• data
  an array (X/count (-E))/Indepen where Indepen is the array obtained from he products of the margins
• met
  a list wherein each entry is the vector of the corresponding margins i.e. apply(X,i,sum)/count
• count
  is the total sum sum(X).
