Infectious Disease Modeling of Social Contagion in Networks
Parameter measurements for obesity from each set of consecutive exams. Data point at exam N represents the value for the transition from exam N to N+1. Error bars are 95 confidence intervals on measurements from regression of transition probability versus number of contacts of a certain type. (A) Contact-independent rates. The rate of recovery () appears to be constant within the margins of error throughout the study while the rate of automatic infection () appears to increase between exams 1 and 3, then stay constant. (B) The contact-dependent transmission rate () appears to increase over time.
