Fit multivariate models predicting T. cruzi infection in children 18 years and younger in the community of Guadalupe, Arequipa, Peru, 2005

��'s are coefficients of the fit models, X's are observations for each child. Subscripts describe the variables age = age of child, an = animal sleeping inside the domestic area, vp = Domestic vectors present, vd = Domestic vector density, tc = Domestic T. cruzi-infected vector present. �� is the intercept of the model, and ��j is the spatial random effect assigned to each household (denoted by the subscript j).
