“…For a number of variables to be used as a poverty proxy, Grosh and Baker (1995) studied by using Living Standards Measurement Survey data in Jamaica, Bolivia and Peru, where they found that more information was preferred to less, although there were diminishing returns for more information added. This diminishing return also found in study by Bah, Bazzi, Sumarto, and Tobias (2018) where she found that out of 340 candidate variables, using a model random sampling method to select good predictions of household welfare in Indonesia, the best model to predict poverty in terms of undercoverage rate was the model with total 20 predicting variables. Also, Schreiner (2008aSchreiner ( , 2009Schreiner ( , 2010aSchreiner ( , 2011Schreiner ( , 2012aSchreiner ( , 2016 developed a Poverty Probability Index (PPI) to be used as a poverty scorecard by using only 10 household characteristic variables to simplify the questionnaire and to reduce cost of data collecting.…”
