Contains functions for 'specific' Multiple Correspondence Analysis,
Class Specific Analysis, Multiple Factor Analysis, 'standardized' MCA, computing and plotting structuring factors and concentration ellipses,
inductive tests and others tools for Geometric Data Analysis (Le Roux & Rouanet (2005) ). It also provides functions
for the translation of logit models coefficients into percentages (Deauvieau (2010) ), weighted contingency tables, an association
measure for contingency tables ("Percentages of Maximum Deviation from Independence", aka PEM, see Cibois (1993) ) and some tools to measure bivariate associations between variables
(phi, Cramr V, correlation coefficient, eta-squared...).
News
========
Version 1.4
New functions:
translate.logit(): translates logit models coefficients into percentages
tabcontrib(): displays the categories contributing most to MCA dimensions
Changes in existing functions:
varsup(): with csMCA, the length of variable argument can be equal to the size of the cloud or the subcloud
textvarsup(): with csMCA, the length of variable argument can be equal to the size of the cloud or the subcloud
conc.ellipse(): with csMCA, the length of variable argument can be equal to the size of the cloud or the subcloud
plot.multiMCA(): 'threshold' argument, aimed at selecting the categories most associated to axes
plot.stMCA(): 'threshold' argument, aimed at selecting the categories most associated to axes
========
Version 1.3
Changes in existing functions:
dimdesc.MCA(): now uses weights
Bug fixes:
dimdesc.MCA(): problem of compatibility next to a FactoMineR update
========
Version 1.2
New functions:
dimvtest(): computes test-values for supplementary variables
Changes in existing functions:
dimeta2(): now allows 'stMCA' objects
========
Version 1.1
New functions:
wtable(): works as table() but allows weights and shows NAs as default
prop.wtable(): works as prop.table() but allows weights and shows NAs as default
Changes in existing functions:
multiMCA(): RV computation is now an option, with FALSE as default,
which makes the function execute faster
Bug fixes:
textvarsup(): there was an error with the supplementary
variable labels when resmca was of class "csMCA".
Error fixes:
textvarsup(): plots supplementary variables on the cloud of categories (and not
the cloud of individuals as it was mentioned in help).
