### Multiple stages:
d3 <- sim_multi_stage(5e2, seed = 1)
pd3 <- policy_data(data = d3$stage_data,
baseline_data = d3$baseline_data,
type = "long",
id = "id",
stage = "stage",
event = "event",
action = "A",
utility = "U")
pd3
# state/Markov type history variable names (H):
get_history_names(pd3)
# full history variable names (H_k) at stage 2:
get_history_names(pd3, stage = 2)
