*>****************************************************************************

*>***********
*

*>The main modifications in the version 98 concern:
*

*>
*

*>1) Correspondence analysis of correspondence with a column of reference, in
*

*>the CA family on models (Escofier, B. 1984. Analyse factorielle en
*

*>référence à un modèle.
*

*>Applications à l'analyse d'un tableau d'échanges. Revue de Statistique
*

*>Appliquée: 32, 4, 25-36). Implementation in COA: ColumnReference,
*

*>Detailed explanations in the form Thema2C.
*

*>
*

*>2) PCA on fuzzy variables. The question is posed by the manipulation
*

*>of species-traits or species-ecological profiles tables. The option
*

*>FuzzyVar: Fuzzy Centring centers these tables in a logic of PCA. The
*

*>option PCA: Fuzzy PCA makes a PCA centered using assistance with the
*

*>specific interpretation. These options allow to process these tables by
*

*>way of K-sets methods. This operation is explained in the form Thema81
*

*>(Part 8 - under way development). The option Tables: FuzzyVariables
*

*>allows to visualize these tables.
*

*>
*

*>3) Classic canonical analysis. It is available in Canonical: Canonical
*

*>correlations Analysis. The option reproduces the essential of calculations
*

*>described in the work of reference (Gittins, R. 1985. Canonical analysis, a
*

*>review with applications in ecology. Springer-Verlag, Berlin. 1-351)
*

*>
*

*>4) Generalized canonical analysis, extension of the previous analysis for
*

*>K-tables (Carrol, J.D. 1968. A generalization of canonical correlation
*

*>analysis to three or more sets of variables. Proceeding of the 76th
*

*>Convention of the American
*

*>Psychological Association: 3, 227-228). Interpretation assistance
*

*>uses proposals of Casin, Ph. & Turlot, J.C. 1986. Une présentation de
*

*>l'analyse canonique généralisée dans l'espace des individus. Revue de
*

*>Statistique Appliquée: XXXV, 3, 65-75.
*

*>
*

*>5) Matrices of correlation between tables. Canonical: CC coefficients
*

*>calculates matrices of correlation coefficients of the canonical
*

*>analysis, Canonical: RLS coefficients calculates matrices of coefficient
*

*>RLS (Kiers, H.A.L, Cléroux, R. & Ten Berge, M.F. (1994) Generalized
*

*>analysis based on optimizing matrix correlations and a relation with IDIOSCAL.
*

*>Computational Statistics and Data Analysis: 18, 331-340) and Canonical:
*

*>RV coefficients calculates matrices of RV coefficents. This last option is
*

*>a lightened version of the program ACT-STATIS centered on the
*

*>investigation of the interstructure. The module form gives definitions and
*

*>references.
*

*>Thank you to H. Kiers for its theoretical indications reported
*

*>in the module form.
*

*>
*

*>6) Processing of lists of occurrences. The module OccurData allows to
*

*>approach ecological data when there are no longer samples, but solely
*

*>lists of occurrences (for example the recording of collection copies, the
*

*>plant collections,Š). OccurData: Read_Occur_File initiates procedures,
*

*>OccurData: CANOCO-Classes analyzes the list of occurrences according to a
*

*>partition (for example geographical), OccurData: CANOCO-Table analyzes the
*

*>list of occurrences when one has
*

*>environmental records associated to each occurrence, OccurData:
*

*>CANOCO-Subspace makes the same thing by using projeciton. The form Thema49
*

*>gives reasons for the choice of CANOCO as title of these analyses because
*

*>proposed analyses are true canonical analyses. This allows to indicate in
*

*>the form Thema4A when and why canonical correspondence analysis is a
*

*>canonical analysis. These innovations are part of the thesis of C.
*

*>Gimaret. OccurData: Array_to_Occur allows to transform the
*

*>species-by-samples tables in list of occurrences and to see that to choose
*

*>the CA and the CCA in ecology it is essentially considered that the
*

*>statistical unit is rather the occurrence of a taxon than the sample
*

*>itself. Such tools were formerly introduced by Green, R.H. 1971. A
*

*>multivariate statistical approach to the Hutchinsonian niche: bivalve
*

*>Molluscs of Central Canada. Ecology: 52, 543-556.
*

*>
*

*>7) Analysis of the match between K tables and one table. The module
*

*>K+1 allows to introduce operators of co - inertia (X1, Y), (X2, Y),Š, (Xk,
*

*>Y) in an analysis of multiple coinertia analysis what finds the analysis of
*

*>concordances of Lafosse, R. & Hanafi, M. 1997. Concordance d'un tableau
*

*>avec K tableaux: définition de K+1 uples synthétiques. Revue de
*

*>Statistique Appliquée: (in press). With these implementations, ADE-4
*

*>contains now a panoply complete enough of K-sets methods.
*

*>
*

*>Miscellaneous modifications:
*

*>
*

*>CategVar: Read Categ File
*

*>files moda.cat and moda.123 are in option
*

*>
*

*>COA: Internal COA
*

*>formats of publishing were improved
*

*>
*

*>FilesUtil: Row_Duplicate
*

*>to copy rows of a table in function of a qualitative variable (tsee the
*

*>card of the pile info.hyp)
*

*>
*

*>Graph1D: Match_2_var
*

*>to represent two numerical codes on one axis (example Thema49 p. 24)
*

*>
*

*>Graph1D: Between_Graph
*

*>to represent a numerical code on one axis according to a partition (example
*

*>Thema49 p. 26)
*

*

*>to represent two numerical codes on one axis (after standardization)
*

*>Levels: Evenly spaced values

*

*>
*

*>OccurData: Rare_Species
*

*>to extract rare species from a list of occurences
*

*>
*

*>Projectors: XY- > Orthonormal Basis - to get an orthonormal basis from
*

*>polynomials in x and y and to introduce the spatial coordinates in
*

*>canonical analyses (Wartenberg, D.E. 1985a. Canonical trend surface
*

*>analysis: a method for describing geographic

*>pattern. Systematic Zoology: 34 (3), 259-279)
