wINEQ 1.2.0 (2023-04-22)

New features

• Package has been enriched with new inequality measures for variables on an ordinal scale, that is:
  • Apouey index
  • Abul Naga and Yalcin index
  • Blair and Lacy ndex
• Functions ineq.weighted and ineq.weighted.boot now start with assessing if variable of interest is numeric whether ordered factor. Then the inequality measures appropriate for the given variable are returned.
• New function medianF returns median for an ordered factor.

Changes

• Improvement of handling with missing data or wrong data format.
• Allison and Foster index formula is not suitable for an ordered factor. Hence, function AF converts an ordered factor variable to numeric variable and then performs calculation.

wINEQ 1.1.2 (2023-02-16)

Bugs fixed

• Function ineq.weighted.boot worked incorrectly for calibrated bootstrap storing results in an object of wrong dimensions.

Changes

• Function ineq.weighted.boot returns named list to access its items easily.

Future works

• more inequality measures for ordinal data

wINEQ 1.1.1 (2023-01-13)

Changes

• R Documentation is enriched with formula for each inequality measure, more details and more references.
• Leti function works for numerical and now also for ordered factor variable.
• A warning was added for Kolm formula that the result is scale dependent. Example provided. Kolm function is enriched with some standardization methods.

New features

• Added new data Well_being - data from sample survey on quality of life conducted on Polish-Ukrainian border. Modified due to SDC.
• Added new data Tourism - data from sample survey on trips conducted in Polish households. Modified due to SDC.
• Added examples for new datasets.

Bugs fixed

• Function ineq.weighted.boot did not take a default bounds parameter for calib function. Now bounds parameter is added with default values.
• Leti function incorrectly calculated a cumulative distribution. Fixed.
• Leti function standardized its results to unit interval without option to change it. Additional parameter norm provided.
