A much less well-known project that takes a unique algebraic approach to modelling (including methods such as agent based models) would be the apophenia library, implemented in C.\n\ngithub.com\n\n### GitHub - b-k/apophenia: A C library for statistical and scientific...\n\nA C library for statistical and scientific computing\n\nA hard copy book on its philosophy was published by Princeton University Press\n\nmodelingwithdata.org\n\n### Modeling with Data\n\nFinally, a U.S. Census technical paper on an Algebra of Statistical Models\n\narXiv.org\n\n### A Useful Algebraic System of Statistical Models\n\nThis paper proposes a single form for statistical models that accommodates a broad range of models, from ordinary least squares to agent-based microsimulations.
