(Package: confreq) :
Configural Frequencies Analysis Using Log-linear Modeling
The package confreq offers some functions for Configural Frequencies Analysis (CFA) proposed by G.A. Lienert as an analysis of types and antitypes of persons or objects grouped according to their characteristic (response) pattern. The core principle in the package confreq is to use the function glm to compute the expected counts based on a model (design) matrix. The main functions are CFA and S2CFA (see details).

CFA
(Package: confreq) :
Configural Frequencies Analysis Main Function
Calculates various coefficients for the Configural Frequencies Analysis (CFA) defining main- and (optionaly) interaction effects. The core principle is to use glm in package stats to calculate the expected counts considering a designmatrix, which is constructed based on an formular definition given in argument form.
