Methods tested.

Method	Structural identification	Parameters estimation
MOM-RL	PAFC asymptotic confidence interval.; Criterion: for a period 𝑚, the procedure looks for the largest order 𝑖 so that all 𝜙^𝑚𝑘𝑘 estimations for 𝑘>𝑖 are not significant.	MOM; (point estimates)
BMOM-RL	PACF Bootstrap confidence interval for each lag.; Criterion: the same as that of MOM-RL.	MOM; (point estimates)
MOM-LR	PAFC asymptotic confidence interval.; Criterion: for a period m, the procedure looks for the largest order i so that all 𝜙^𝑚𝑘𝑘 estimations for 𝑘<𝑖 are significant. This criterion does not admit nonsignificant intermediary lags.	MOM; (point estimates)
PBMOM	PACF Bootstrap confidence interval for each lag.; Criterion: the same as that of MOM-LR.	MOM; (Bootstrap confidence intervals)
