sqrttriangle-ergmTerm-c7f8ea09: Square root of the number of triangles

In statnet/ergm.userterms: User-specified Terms for the statnet Suite of Packages

Square root of the number of triangles

Description

These terms add one network statistic to the model, the square root of the number of triangles. They demonstrate the private and auxiliary storage mechanisms. The change statistic for the square root of the number of triangles depends on the initial number of triangles, so it is costly to compute – unless one can keep track of the number of triangles. These terms can only be used with undirected networks.

Usage

# binary: sqrt.triangle

# binary: sqrt.triangle.aux
