CA is inherently weighted so no need to do that for counts.

Hi
I didn't find an option in PCA/CA/FAMD functions for dealing with weighted
data points.
Assume for a variable (V1), the value of the first individual (X) is 86%
and the value of the second individual (Y) is 3% and so on. I would like to
assign a weight vector like (0.55, 0.12, ...) to them. Any idea about that?
 
Regards,
Mahmood

You can use the subcommand row.w. Example below: 23 individuals with 23 different weights.
 
res<-PCA(Dataset.PCA , scale.unit=TRUE, ncp=5, quali.sup=c(94: 94), graph = FALSE,
 
row.w=c(0.033433509,0.034560481,0.023290759,0.025169046,0.016904583,0.013899324,0.196093163,0.063110443,0.046957175,0.043576258,
 
0.043200601,0.03756574,0.16904583,0.053719008,0.030052592,0.019158527,0.017655898,0.00864012,0.033433509,0.040570999,
 
0.024793388,0.007513148,0.017655898))
 

 
row.w an optional row weights (by default, a vector of 1 for uniform row weights); the weights are given only for the active individuals
