Latent Network Models to Account for Noisy, Multiply-Reported Social Network Data

# π Is this package for me?

Suppose you want to find out the βtrueβ network of social ties between \(n\) individuals and you query \(m\) βreportersβ within this network (where \(m \le n\)) about such ties. These ties could, for instance, represent relationships commonly studied in the social sciences β such as loaning money, giving advice, or sharing food.

Suppose, also, that you ask them questions in both directions: βWho does person \(i\) *borrow* money *from*?β and βWho does person \(i\) *lend* money *to*?β As it is doubtful that the responses given by the reporters will match perfectly, you will almost surely end up with varying perspectives on what should be the same relationship and, so too, varying perspectives on the structure of the overall social network. The question then is, how do you make sense of this data in the face of inconsistent reports and potentially unreliable reporters?

The model in the **VIMuRe** package is our proposed solution to this problem. It fits a latent network model from multiply-sampled social network data using Bayesian inference, returning a posterior distribution that can later be used to obtain samples or a point-estimate network (e.g., as an igraph object). The package was written in Python and R and is available on GitHub (https://github.com/latentnetworks/vimure).

## π In brief

**Input:**multiply-sampled social network data as an edgelist or an igraph object.**Output:**a fitted latent network model that can be used to obtain samples or a point-estimate network (an igraph object) from the posterior distribution of the fitted model.
