In soc.ca: Specific Correspondence Analysis for the Social Sciences

Description

Different forms of contribution summaries for soc.ca objects. Results are presented according to the specified mode

Usage

contribution(
  object,
  dim = 1,
  all = FALSE,
  indices = FALSE,
  mode = "sort",
  matrix.output = FALSE
)

Arguments

object	a soc.ca object
dim	the included dimensions
all	If TRUE returns all modalities instead of just those that contribute above average
indices	If TRUE; returns a vector with the row indices of the modalities or individuals
mode	indicates which form of output. Possible values: "sort", "mod", "ind", "variable". If the mode is "variable", dim can be a sequence of dimensions: 1:5
matrix.output	if TRUE; returns output as a matrix instead of as printed output.

Value

Each mode prints different results:

"mod"	Ranks all modalities according to their contribution
"sort"	Ranks all modalities according to their contribution and then sorts them according to their coordinates
"ind"	Ranks all individuals according to their contribution
"variable"	Sorts all modalities according to their variable and sums the contributions per variable

The values reported:

Ctr	Contribution values in percentage. Contribution values for individuals are reported in permille
Coord	Principal coordinates
Cor	The correlation with the dimension
