## Theoretical maximum for degree centralization

### Description

See centralize for a summary of graph centralization.

### Usage

centr_degree_tmax(
graph = NULL,
nodes = 0,
mode = c("all", "out", "in", "total"),
loops = FALSE
)


### Arguments

 graph The input graph. It can also be NULL, if nodes, mode and loops are all given. nodes The number of vertices. This is ignored if the graph is given. mode This is the same as the mode argument of degree. loops Logical scalar, whether to consider loops edges when calculating the degree. Currently the default value is FALSE, but this argument will be required from igraph 1.4.0.

### Value

Real scalar, the theoretical maximum (unnormalized) graph degree centrality score for graphs with given order and other parameters.
