compare_robustness {robber}

Compare the robustness for different LBM parameters

Description

This function is designed to be used with a list of parameters as the one given by the function get_lbm_param(). The default parameters are designed such that the return value for a uniform extinction sequence is bounded above by 0.5.

Usage

compare_robustness(
  list_param,
  dens = 0.0156,
  new_nr = 100,
  new_nc = 100,
  ext_seq = "uniform"
)

Arguments

list_param

A list of list of LBM parameters, each list must contain at list con, pi and rho entries, such as the one returned by the function get_lbm_param(). The size of the network is optional.

dens

The density (connectance) used to compare the network. The com parameters of list_param will be normalized so that the average probability of interaction in the network is equal to dens. Default to 0.0156.

new_nr

The number of rows of the normalized networks. Default to 100.

new_nc

The number of columns of the normalized networks. Default to 100.

ext_seq

The distribution of the primary extinction sequence used to compare the networks. One of c("uniform", "decreasing", "increasing"). Default to "uniform".

Value

A list of the sames length as list_param, the robustness (AUC) after normalization for all set of parameters.

Examples

par1 <- list(con = matrix(c(.5,.3,.3,.1), 2, 2),
             pi  = c(.25,.75),
             rho = c(1/3, 2/3))
par2 <- list(con = matrix(c(.4,.1,.1,.4), 2, 2),
             pi  = c(.25,.75),
             rho = c(1/2, 1/2))
compare_robustness(list_param = list(par1, par2), ext_seq = "decreasing")
compare_robustness(list_param = list(par1, par2), ext_seq = "increasing")
