panel_qtt_long_agg: QTT Aggregation for pre_copula = "long"

In qte: Quantile Treatment Effects

QTT Aggregation for pre_copula = "long"

Description

Custom aggte_fun for ptetools::pte that handles the two-step weight renormalization needed when pre_copula = "long": some (g,t) cells are structurally uncomputable (their pre2 does not exist in the data), and those cells must be excluded from aggregation with proper weight redistribution.

Two-step weights (overall):

1. Identify surviving groups (those with at least one valid post-treatment cell); renormalize p_g among those groups only.

2. Within each surviving group, assign equal weight p_g / |\text{valid cells for } g| to each valid post-treatment cell.

Dynamic (event-study) weights: for each event time e, renormalize p_g among groups where (g, g+e) is valid.

Error behaviour: if a structurally valid cell returns NA att, the function errors immediately — such NAs indicate a bug in panel_qtt_gt, not a structural limitation.

Usage

panel_qtt_long_agg(attgt.list, ptep, extra_gt_returns)

Arguments

attgt.list	List of per-cell attgt results from compute.pte.
ptep	ptetools parameter environment.
extra_gt_returns	List of per-cell extra returns (F0, F1, Fte ECDFs).

Value

A list with overall_results, dyn_results, group_results, attgt_results, F0_overall, F1_overall — matching the structure returned by ptetools::qtt_pte_aggregations.
