submatrix

This dataset represents a subset of the causal relationships defining a five-variable system.  Specifically, it contains the second, third and fourth variable of the dataset <code>community.matrix</code>.

datasets

Loop analysis makes qualitative predictions of variable change in a system of causally interdependent variabless, where "qualitative" means sign only (i.e. increases, decreases, non change, and ambiguous). This implementation includes output support for graphs in .dot file format for use with visualization software such as graphviz (graphviz.org). Loop Analyst provides tools for the construction and output of community matrices, computation and output of community effect matrices, tables of correlations, adjoint, absolute feedback, weighted feedback and weighted prediction matrices, and feedback, path and loop enumeration tools.

A 3 by 3 (-1, 0, 1) matrix.  The matrix is interpreted as the jth variable has the direct causal effect a[i,j] on i.
