%description
The social network literature features numerous methods for assigning
value to paths as a function of their ties. 'gretel' systemizes these
approaches, casting them as instances of a generalized path value function
indexed by a penalty parameter. The package also calculates probabilistic
path value and identifies optimal paths in either value framework.
Finally, proximity matrices can be generated in these frameworks that
capture high-order connections overlooked in primitive adjacency
sociomatrices. Novel methods are described in Buch (2019)
<https://davidbuch.github.io/analyzing-networks-with-gretel.html>. More
traditional methods are also implemented, as described in Yang, Knoke
(2001) <doi:10.1016/S0378-8733(01)00043-0>.
