Description
Builds transition/succession matrices (lag analysis), compares several matrices. Plane drawing of flow charts obtained from those matrices by a method based on a modified Correspondence Analysis (CA). The modification consists in symmetrising the matrix and loading its diagonal following Foucart (1985) and Van der Heijden (1986). This leads to a 'nice' positionning of the edges of the graph, representing the different items in succession. 'Smart' arrows are drawn as vertices.
Details
read.series.seq reads a series of sequences, each of them considered as an identifiers list. compseq compares the sequences by likelihood ratio tests (LRT) with a Bonferroni correction. The LRT serve to build a distance matrix of the sequences two-by-two. This matrix of distance is used both for a clustering of them and for a mapping by Principal Coordinates Analysis (PCA) also called Multidimensional Scaling (MDS).
From the sequences a transition matrix is obtained. symet symmetrises and/or loads its diagonal. ca makes a Correspondence Analysis and saves the factorial coordinates as an object. flux draws the transition graph. The complete analysis chain is the following:
read.series.seq -> compseq -> symet -> ca -> flux
A sketch of the method is given in Pierre and Kasper (1990).
