Table 2 Regression coefficients for home range area and defecation sites in home range. Bivariate and multivariate linear regression models for log-area of home range, and negative binomial models for the number of open defecation sites within home ranges

From: Seasonal patterns in risk factors for Taenia solium transmission: a GPS tracking study of pigs and open human defecation in northern Peru
