parameters 0.18.2

New functions

• New function dominance_analysis(), to compute dominance analysis
  statistics and designations.

Changes to functions

• Argument ci_random in model_parameters() defaults to NULL. It uses a
  heuristic to determine if random effects confidence intervals are likely to
  take a long time to compute, and automatically includes or excludes those
  confidence intervals. Set ci_random to TRUE or FALSE to explicitly
  calculate or omit confidence intervals for random effects.

Bug fixes

• Fix issues in pool_parameters() for certain models with special components
  (like MASS::polr()), that failed when argument component was set to
  "conditional" (the default).

• Fix issues in model_parameters() for multiple imputation models from
  package Hmisc.
