Files description

• nPSO_model.m
  Implementation of the Popularity-Similarity-Optimization generative model with nonuniform (nPSO) or uniform (PSO) distribution of angular coordinates.

• create_mixture_gaussian_gamma_pdf.m
  Generation of Gaussian and Gamma mixture distribution with C components, as described in the Supplementary Information of the reference.

• example_usage.m
  Example usage of the previous functions, the script generates and plots four examples:

  • nPSO model with 4 communities and default Gaussian mixture distribution
  • nPSO model with 4 communities and custom Gaussian mixture distribution
  • nPSO model with 8 communities and custom mixture distribution (Gaussian and Gamma mixture distribution)
  • PSO model
