Growth trajectories before/after a scaling event ("transitions" and "evolutions")

Translates n1_3_persistence.do (Pseudocode/n1_3_persistence.md). Computes two related classification schemes: transitions (2014-2016 scaler cohorts, follow-up only) and evolutions (2017 cohort, both lead-up and follow-up, further split by entrant/incumbent/exiting status). Iterates over 8 (hgstub, def) HGF-definition combinations, each starting fresh from accounts_indicators — nothing computed for one combination carries into the next.

Usage

compute_persistence(config, accounts_indicators)

Arguments

config

A scaleup_config from config_scaleup().

accounts_indicators

The output of build_accounts_indicators().

Value

A named list with up to 3 elements — transitions, evolutions_p1, evolutions_p2 — each a data frame matching PDF Table 3.4, or absent from the list if this country's panel was too short to satisfy any (hgstub, def) combination's length requirement for that output (mirrors the source: a short panel may produce none of the 3 CSVs).
