Summary of ridge regression models.

For each response variable, namely mortality, infection status, infection status for 10 or more individuals, infection status determined from PCR tests only and infection status predicted for free-ranging mammals, table summarizes the t-statistic of coefficient estimates of predictors and accompanying p-value. Coefficients for 31 eigenvectors (c1-c31) provided in table even though model was run with the first 48 phylogenetic eigenvectors; higher eigenvector coefficients for variables c32-c48 were always non-significant and therefore excluded from table. Bold faced numbers represent significance at α of 0.05. Italicized numbers represent significance at α of 0.1. NA represents coefficients that were not fit in model.
