Method new()

constructor for simpleSBM_fit for missSBM purpose

Usage

SimpleSBM_fit_MNAR$new(networkData, clusterInit)

Arguments

networkData

a structure to store network under missing data condition: either a matrix possibly with NA, or a missSBM:::partlyObservedNetwork

clusterInit

Initial clustering: a vector with size ncol(adjacencyMatrix), providing a user-defined clustering with nbBlocks levels.

---

Method update_parameters()

update parameters estimation (M-step)

Usage

SimpleSBM_fit_MNAR$update_parameters(nu = NULL)

Arguments

nu

currently imputed values

---

Method update_blocks()

update variational estimation of blocks (VE-step)

Usage

SimpleSBM_fit_MNAR$update_blocks(log_lambda = 0)

Arguments

log_lambda

additional term sampling dependent used to de-bias estimation of tau

The objects of this class are cloneable with this method.

Usage

SimpleSBM_fit_MNAR$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
