This paper constitutes a first step towards an extension of correspondence analysis with fuzzy data (FCA). At this stage, our main objective is to lay down the algebraic foundations for this fuzzy extension of the usual correspondence analysis. A two-step method is introduced to convert the fuzzy eigenvalue problem to an ordinary one. We consider a fuzzy(More)
In this paper the main problem is the generalization of the fuzzy eigenvalue problem of Fuzzy Correspondence Analysis (FCA). We investigate the algebraic foundation of finding fuzzy eigenvalues-eigenvectors of a FCA-fuzzy matrix in some more complex cases. We continue to utilize the two-step method with triangular fuzzy numbers introduced in [20], to(More)
