This is the powerpoint and in-class activities (including datast) used in the short training course offered at the 2011 Political Networks meeting at the University of Michigan. The course lasted three hours, although the material could be expanded or shortened as needed.  The first two hours covered the traditional approach to survey-based netework analysis: pros and cons of egonet or sample survey based research, the core discussants name generator and name interpreters, data transformation into long and wide formats, non-response in egocentric network studies, calculations of network size and network composition measures, respondent misperception of discussants, examples of the use of egocentric networks in studies of participation and influnce, and the drawbacks of the traditional approach.  The last hour covered more recent developments in survey-based analysis that use measures of theoretical mechanisms or predictons derived from formal models of network-based decision-making

The slides include the syntax to some basic exercises with egocentric or survey-based network data collections, and the data used in the slide is also attached.  There is also a syntax file for use if needed.  (Note that there may be some mistakes in the syntax in the powerpoint, and it should be checked thoroughly prior to use.)
