- gaussian_random_partition_graph(n, s, v, p_in, p_out, directed=False, seed=None)[source]#
Generate a Gaussian random partition graph.
A Gaussian random partition graph is created by creating k partitions each with a size drawn from a normal distribution with mean s and variance s/v. Nodes are connected within clusters with probability p_in and between clusters with probability p_out
Number of nodes in the graph
Mean cluster size
Shape parameter. The variance of cluster size distribution is s/v.
Probability of intra cluster connection.
Probability of inter cluster connection.
- directedboolean, optional default=False
Whether to create a directed graph or not
- seedinteger, random_state, or None (default)
Indicator of random number generation state. See Randomness.
- GNetworkX Graph or DiGraph
gaussian random partition graph
If s is > n If p_in or p_out is not in [0,1]
Note the number of partitions is dependent on s,v and n, and that the last partition may be considerably smaller, as it is sized to simply fill out the nodes
