HMFA: Hierarchical Multiple Factor Analysis

Description

Performs a hierarchical multiple factor analysis, using an object of class list of data.frame.

Usage

HMFA(X,H,type = rep("s", length(H[[1]])), ncp = 5, graph = TRUE, axes = c(1,2), name.group = NULL)

Arguments

X

a data.frame

H

a list with one vector for each hierarchical level; in each vector the number of variables or the number of group constituting the group

type

the type of variables in each group in the first partition; three possibilities: "c" or "s" for quantitative variables (the difference is that for "s", the variables are scaled in the program), "n" for categorical variables; by default, all the variables are quantitative and the variables are scaled unit

ncp

number of dimensions kept in the results (by default 5)

graph

boolean, if TRUE a graph is displayed

axes

a length 2 vector specifying the components to plot

name.group

a list of vector containing the name of the groups for each level of the hierarchy (by default, NULL and the group are named L1.G1, L1.G2 and so on)

Value

Returns a list including:
