Table 2 in Factors affecting site selection by beavers colonizing streams in the upper Midwest region of the United States

Table 2. Parameter estimates (coefficient) and related statistics for the best American beaver (Castor canadensis) habitat selection logistic regression model using geomorphology variables. Categorical variables were parameterized as (0, 1); therefore, the value of the category not listed in the table is embedded in the intercept. SE = standard error.
