Background

In a famous study, known as the Columbia University Drug Study, the diffusion of a new drug (gammanym) was investigated. The researchers collected data on the first subscription of this drug by physicians in several communities. In addition, they investigated friendship ties and discussion links between the physicians, asking them to name three doctors whom they considered to be personal friends and to nominate three doctors with whom they would choose to discuss medical matters.
The friendship and discussion ties among 31 physicians are coded into separate networks. The partition Galesburg_adoptiontime.clu specifies the number of months since the introduction of the new drug at which the physician first prescribed the drug. This is considered to be their adoption time.
