risk_transmission: modeling the risk transmission of the trade network

In zlfccnu/econophysics: Functions for econophysics

Description

modeling the risk transmission of the trade network

Usage

risk_transmission(
  net,
  mode = c("Node_driven", "Edge_driven"),
  n_id = NULL,
  e_id = NULL,
  alpha = 0.1,
  alpha_lower_limit = 0.1,
  alpha_increase_type = c("export", "degree"),
  return_net = FALSE
)

Arguments

net	a tidygraph object
mode	two different supply shock scenario
n_id	the initial shocked node id
e_id	the initial shocked edge id
alpha	the threshold above which the infected nodes during the transmission process will change into active state, the default is 0.1, if it is NULL, the alpha value for each country will be scaled to [alpha_lower_limit,1] based on the export value or the degree of each country.
alpha_lower_limit	the lower limit of the alpha value range when alpha=NULL.
alpha_increase_type	export or degree, in the mitigate scenario, export means we will increase the alpha according to the export volume, degree means the alpha parameter will increase according to the node degree
return_net	whether return the final network structure or not

Value

the active node size for each iteration
