Compute Variance Inflation Factors for an unmarkedFit Object.
Compute the variance inflation factors (VIFs) for covariates in one level of the
model (i.e., occupancy or detection). Calculation of VIFs follows the approach
of function vif in package car, using the correlation matrix of
fitted model parameters.
