Moreover I cannot find a file which may contain correlation ratios

between each categorical variable and each factorial score of the

coinertia-analysis.

*>>>>>>>>>>>>>

I have also the impression that FCA and other programs also do not create

a file such as this

CorRatioFCA: Correlation ratios after a FCA

Title of the analysis: C:\ade4\COLEOP\ESF.fl

Number of rows: 110, columns: 9

I agree with you, that other coinertia analyses are needed

but I have not well understood what matrices you really intend to use in

the other coinertia

analysis
