Adaptive item log accessor.

Source: R/adaptive_print.R
adaptive_item_log.Rd

Adaptive item log accessor.

Usage

adaptive_item_log(state, refit_id = NULL, stack = FALSE)

Arguments

state

Adaptive state.

refit_id

Optional refit index.

stack

When TRUE, stack all refits.

Value

A tibble of item-level summaries. When stack = FALSE, one row per item for the selected refit. When stack = TRUE, one row per item per refit with refit_id identifying source refit.

Details

item_log stores per-item posterior summaries by refit. The underlying state stores a list of refit tables; this accessor can return one refit table (default: most recent) or stack all refits into a single tibble.

Item-level summaries are domain-explicit:

  • theta_raw_*: raw/within-set posterior summaries (EAP, fixed quantiles, SD, rank) at the current refit.

  • theta_link_*: linked/global posterior summaries (EAP, fixed quantiles, SD, rank) after transform application.

  • During linking Phase A (phase_scope = "phase_a_set"), theta_link_* is typed NA by design.

  • phase_scope, phase_scope_set_id, and in_phase_scope indicate which item domain is currently optimized.
