Changes in version 0.3.0 (2025-01-13)                  

  - Safeguard against invalid indexes when accessing the ranking
    variable in the decomposition analysis by checking the length and
    for NA at indexes used by the model matrix.
  - Add additional rank function rank_gwt that implements the
    generalized version of the weighted fractional as suggested in van
    Ourti 2004, and using it for the concentration index leads to
    results compatible with Stata's conindex. It can be enabled with a
    new parameter in ci();, rank_function = rank_gwt() that for
    compatibility has default value rank_wt().
  - Fix cox proportional hazard example to not attempt to incorrectly
    discard the intercept (coxph models do not have intercepts). Also
    fix the survival formula syntax to not use explicit :: calls.
  - Fix roxygen documentation syntax for 'correct_sign()'

                 Changes in version 0.2.3 (2023-04-18)                  

  - Further fix issues for CRAN release, related to spelling, policies,
    and documentation
      - documented return value for all functions, even if called for
        side effects
      - FALSE/TRUE instead of T/F
      - safeguarding against altering user options in plot and not
        restoring them
  - Examples for all packages supported decomposition model types
  - Improve handling of whether intercept should be included or not for
    contribution()

                        Changes in version 0.2.2                        

  - Get ready for release on CRAN. Improve spelling, documentation
  - Add imaginary example housing data set to power the examples. The
    previous example data set Nigeria was removed because of uncertainty
    about compatible licensing. No appropriate microdata set with both
    continuous inequality and health outcome variable with an
    appropriate license could be found, hence the artificial data.

                        Changes in version 0.2.1                        

  - improve plotting. Calculate margins to avoid cutting-off labels for
    decomposition, more informative axis labels.

                         Changes in version 0.2                         

  - Forked from (https://github.com/brechtdv/rineq), which in turn was
    forked from decomp
  - Add support for binary type concentration index
  - Add support for robust standard errors, requires the sandwich
    package
  - Add support for different methods of calculating the concentration
    index and briefly outline their pros and cons. See method argument
    of ci()
  - Add support for marginal effects probit (mfx package).
  - Convert documentation to the roxygen2 format.
