Homogeneity analysis

I ask if some one could give me some information about non-linear
multivariate analysis.

In particular I would like to know:

- what is the difference between MCA and HOMALS ?;
- what is the difference between PCA and PRINCALS ?
- are they better method to treat each variable as nominal, quantitative
or ordinal ?

Thank you.
