The Medical Innovation data were stored in file cabinets in a basement
building at Columbia University. Ron Burt (1987) acquired an NSF grant to
develop network diffusion models and retrieve the original surveys and enter
them into a database. He distributed copies of the data on diskette and sent
one to me, Tom Valente, and I imported onto a PC environment.Details
The collected dataset has 125 respondents (doctors), and spans 17 months of data
collected in 1955. Time of adoption of non-adopters has been set to month
18 (see the manual entry titled Difussion Network Datasets).
