We added biv_per_variable() a function to calculate the average bias per variable for the bivariate comparison, and an average bias per variable across comparisons.
We added multi_per_variable() a function to calculate the average bias per coefficient and per model, for the multivariate comparison, and an average biases per coefficient and per model across comparisons.
We implemented better bootstrapping, that will use weighting in every bootstrap iteration, for all main functions (\code{uni_compare}, \code{biv_compare}, \code{multi_compare}.
The functions are much faster during bootstrapping now.
The possibility to weight the dataset to the benchmark using \code{raking} and \code{post-stratification}.
