Source: Authors’ calculations from DESMIGRATIF (2018). Note: The rank represents the importance of each variable from Random Forest prediction models implemented separately for women and men with 1000 iterations and 327 variables. The rate of appearance in LASSO Stability Selection is obtained from implementing 1000 LASSO iterations with the 327 variables and calculating the occurrence of each variable in each LASSO iteration.
