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

β'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. α is the intercept of the model, and φj is the spatial random effect assigned to each household (denoted by the subscript j).
