predict.mmsbm: Predict edges based on estimated mmsbm model

In NetMix: Dynamic Mixed-Membership Network Regression Model

Predict edges based on estimated mmsbm model

Description

The function produces expected posterior edges based on estimated parameters and (optionally new) predictor data

Usage

## S3 method for class 'mmsbm'
predict(
  object,
  new.data.dyad = NULL,
  new.data.monad = NULL,
  forecast = FALSE,
  type = c("link", "response", "mm"),
  ...
)

Arguments

object	Object of class mmsbm.
new.data.dyad	An optional data.frame object.
new.data.monad	An optional data.frame object.
forecast	Boolean. Should prediction forcast one step into the future? Defaults to FALSE.
type	Character string. The default is to use the linear predictor of edges. The alternative "response" returns predicted probabilities. The alternative "mm" returns predicted mixed-membership vectors.
...	Currently ignored

Value

If new.data.dyad = NULL, vector of length nrow(object$dyadic.data). Else, vector of length nrow(new.data.dyad).

## Load datasets
data("lazega_dyadic")

## Estimate model with 2 groups
lazega_mmsbm <- mmsbm(SocializeWith ~ Coworkers,
                      ~  School + Practice + Status,
                      senderID = "Lawyer1",

                      nodeID = "Lawyer",
                      data.dyad = lazega_dyadic,

                                           hessian = FALSE))

## Get in-sample predicted edge probabilities
lazega_preds <- predict(lazega_mmsbm, type = "response")
