Erratum to: A moderate role for cognitive models in agent-based modeling of cultural change
Complex Adaptive Systems Modeling volume 2, Article number: 1 (2014)
After publication of (Abrams 2013), I discovered errors in two formulas in the settle-nets paragraphs of the POPCO main loop section in Methods (page 13 in the PDF file). I correct these errors here. In the definition of the weighted sum n i of input activations a j from nodes j to node i across links with weights w ij , the direction of the inequality was reversed. The definition of n i should read:
There were also errors in the definition of s i , the weighted sum of a node’s current activation a i and its summed inputs p i and n i across positively and negatively weighted links, respectively. The definition of s i should read as follows:
I regret these errors and hope that they do not cause confusion. Full source code for the version of POPCO used in Abrams (2013) can be found at https://github.com/mars0i/popco.
