Gibbs sampling of dynamic U and V with snap-shift dynamics
Source:R/rUV_dynamic_fc.R
rUV_dynamic_snap_fc.RdLike rUV_dynamic_fc but lets each actor's latent position either drift
under the AR(1) prior or jump under a diffuse N(0, kappa^2) snap prior, chosen
per actor-period by a Gaussian log-marginal model selection.
Usage

delta_u_current = NULL,
delta_v_current = NULL,
shrink = TRUE,
symmetric = FALSE
)Arguments
- U
3D array of current U positions (n x R x T)
- V
3D array of current V positions (n x R x T)
- ET
3D array of residuals (n x n x T)
- rho_uv
AR(1) autoregressive parameter for the drift prior
- sigma_uv
Innovation standard deviation for the drift prior
- s2
dyadic variance
- kappa
diffuse snap-prior standard deviation
- pi_snap
prior snap probability
- delta_u_current
current sender-side snap indicators. If
NULL, a zero matrix is used.- delta_v_current
current receiver-side snap indicators. If
NULL, a zero matrix is used.- shrink
whether to apply shrinkage (default TRUE)
- symmetric
whether the network is symmetric (default FALSE)
