vardi.algorithm

matrix of link loads over time (m x n, one
  column per time)

numeric vector of starting values for OD
  flows (length k)

lambda

Runs moment-matching algorithm of Vardi (1996) until
  convergence

multivariate

models

networkTomography implements the methods developed and
        evaluated in Blocker and Airoldi (2011) and Airoldi and Blocker
        (2012). These include the authors' own dynamic multilevel model
        with calibration based upon a Gaussian state-space model in
        addition to implementations of the methods of Tebaldi & West
        (1998; Poisson-Gamma model with MCMC sampling), Zhang et al.
        (2002; tomogravity), Cao et al. (2000; Gaussian model with
        mean-variance relation), and Vardi (1996; method of moments).
        Data from the 1router network of Cao et al. (2000), the Abilene
        network of Fang et al. (2007), and the CMU network of Blocker
        and Airoldi (2011) are included for testing and
        reproducibility.
