Gifi Methods for Optimal Scaling in R: The Package homals Jan de Leeuw Patrick Mair 2009-08-04 Journal of Statistical Software R package homals which performs homogeneity analysis and various extensions. By setting rank constraints nonlinear principal component analysis can be performed. The variables can be partitioned into sets such that homogeneity analysis is extended to nonlinear canonical correlation analysis or to predictive models which emulate discriminant analysis and regression models. For each model the scale level of the variables can be taken into account by setting level constraints. All algorithms allow for missing values.]]> Statistics Software http://www.jstatsoft.org/v31/i04 http://www.jstatsoft.org/v31/i04/paper Text Software Dataset
