Decision plot of the complete data set. The y-axis represents the variables used in the study, which refer to: Electricit = Presence or absence of electricity; ri_orcd_n = Constructed risk from soil organic carbon content; BSI_n = Bare Soil Index; Clyp_n = Weight percentage of the clay particles; MSI_n = Moisture Stress Index; Phikcl_n = pH index measured in KCl solution; Ocstha_n = Soil organic carbon stock; BLDFIE_n = Bulk density; NDBI_n = Normalized Difference Builtup; Drinking_1 = Source of drinking water during the rainy season; Drinking w = Source of drinking water during drought periods; Phihox_n = pH index measured in water solution; Water cook = Source of water used for cooking; Hand washi = Hand washing, source of water used for hand washing; Domestic animals = Presence or absence of domestic animals; SLTppt_n = Weight percentage of the silt particles; Radio = Presence or absence of radio; Toilet = Type of bath; ri_bfd = Constructed risk from bulk density; Bath = Origin of water used in the bath. The x-axis represents the number of hookworm infected individuals per household which is the output value of the model.
