Probability of huillín sighting (yes/no) (dependent variable), according to the (independent) variables: setting, gender, social group (tourist guides, staff of protected areas, neighbors from San Carlos de Bariloche), age and permanence. The “Estimate” column shows the parameters of the generalized linear regression (GLM) for each independent variable (beta). The reference categories are: setting “rural,” gender “female,” social group “tourist guides,” age “ > 30 years,” permanence “ > 20 years.”
