Description Usage Arguments Value
Requires bounded optimization to maintain positive OD flows, and only those flows that are not deterministically zero should be included in the estimation.
1 | obj.tomogravity(xt, yt, A, srcDstInd, lambda)
|
xt |
length-k numeric vector of point-to-point flows |
yt |
length-m numeric vector of observed aggregate flows |
A |
m x k routing matrix, yt = A xt |
srcDstInd |
list of source and destination flow
indices corresponding to each point-to-point flow, as
produced by |
lambda |
regularization parameter for mutual information prior. Note that this is scaled by the squared total traffic in the objective function before scaling the mututal information prior. |
numeric value of objective function to minimize in tomogravity estimation
