Resumen/ Abstract

Social network studies have increased during the last years in different disciplines, such as communication and computer sciences. These studies have demanded more statistical methodologies to estimate the degree to wich network structures are likely to occur. and explain what endogenous attributes affect the likekihood of new connections. For these reasons. Exponential Random Graph Models (ERGMs) have been referred to as a promising technique for the modeling of social network (Snijders. 2007). and have wide applications in the area of organizational studies and communication studies. ERGMs are a family of statistical models used to test if one or more social structures are more prevalent in the network than would occur by chance alone (Huffaker et al..2009; Robins. Pattison. Kalish. & Lusher.2007). Topics of this talk include examples of social network modeling, the logic of ERGMs. parameter selection and estimation, parameter interpretation, Goodness of Fit, and troubleshooting convergence issues. We will use the package “statnet” (Handcock, Hunter, Butts, Goodreau, & Morris. 2008) to develop these models.
