FitBothMandC function

Fit Matching-Centrality Model

Fit a model that contains both a trait-matching and a centrality term based on Rohr et al. (2016)

FitBothMandC(
  list,
  N_runs = 10,
  maxit = 10000,
  method = "Nelder-Mead",
  ExtraSettings = NULL
)

Arguments

• list: Network List
• N_runs: Number of different start points for k2 and lambda to try. The best (maximum likelihood) half will be used to construct the probability matrix
• maxit: Default = 10'000
• method: Passed to optim, default = 'Nelder-Mead'
• ExtraSettings: Other control settings to pass to optim()

Returns

Network list with added 'B_par',the best fitting parameters, 'M_ProbsMatrix', the probability matrix
