An implementation of a framework for modelling and inferencing the attachment mechanisms of temporal complex networks. For estimating the preferential attachment (PA) function in isolation, we implement Jeong's method, the corrected Newman's method and the PAFit method. For jointly estimating the PA function and node fitnesses, we implement the PAFit method. The package also provides flexible methods to generate a wide range of temporal networks based on PA and fitness. See the accompanying vignette for a tutorial. For a list of references, please run the command: citation("PAFit").
The main functions are:
GenerateNet: generates networks based on the preferential attachment and fitness mechanisms.
GetStatistics: summarizes a matrix of edges into summary statistics ready for estimating the preferential attachment function or node fitness.
Jeong: estimates the preferential attachment in isolation by Jeong's method
Newman_corrected: estimates the preferential attachment in isolation by the corrected Newman's method
PAFit: jointly estimates the preferential attachment function and node fitness
CreateDataCV: creates cross-validation for
performCV: performs cross-validation for selecting regularization parameters of
