BUG FIXING

  • Plots in the DIF/About section of the app were fixed (uniform vs.
    nonuniform DDF is now correctly displayed).
  • Display of the discrimination index ULI was fixed for ordinal items.
  • Bug in display of Multinomial regression parameters in case of the IRT
    parametrization was fixed.
  • In the IRT training section, the calculation and display of item information
    curves was fixed. (Thanks to Hynek Cigler for reporting this issue.)
  • Calculation of minimal scores in the ItemAnalysis() function was fixed.
  • Display of ICC in IRT models was updated to respond to updates in the mirt
    package.
  • In the Regression section of the app, missplaced SE for intercepts and
    slopes were fixed.

MAJOR UPDATES

  • A new section Reliability/Restricted range was added to the app offering
    interactive examples demonstrating issues with reliability estimates in
    restricted-range samples.
  • Continuous items are newly allowed, rater variable was added,
    data upload and warning messages were updated.
  • New function ICCrestricted() for computing ICC in restricted samples was
    added.
  • Functions gDiscrim(), DDplot() and ItemAnalysis() were updated,
    variable names were unified.
  • New function plot_corr() to compute and visualize an item correlation
    matrix was added and implemented within the ShinyItemAnalysis interactive
    app.
  • New datasets AIBS, NIH, HCIgrads, HCItestretest, HCIprepost
    and HCIdata were added.
  • startShinyItemAnalysis() function was fixed to finish job persisting in
    the backgroud after the app is closed.
  • Figures can now be downloaded at once in DDF section of the app.
  • Equations were unified in the Regression, IRT and DIF/Fairness
    sections of the app, with p being the index for person and i being the
    index for an item.
  • Interactive training section was added to the DIF/Fairness section,
    offering interpretation of group-specific models.
  • Figures in the Validity, Regression, IRT, and DIF/Fairness section
    are now displayed in plotly mode in the shiny app.
  • The IRT/Rasch section was restructured and it now offers both the
    intercept/slope as well as the IRT parametrization. (This is planned for
    other IRT subsections in future versions.)
  • The Regression/Multinomial section newly offers also the IRT
    parametrization.

MINOR UPDATES

  • The intropage was updated, new News section was added.
  • Method ordering was updated in the DIF/Fairness section.
  • Toy data selection was updated.
  • Selected R code was updated.
  • Unnecessary dependencies were removed.
  • Summary tab was updated within the app, interactive help with formulae is
    newly offered.
  • Interpretation of IIC for selected theta were added in the IRT/training
    section.
  • styler package was applied on .R files, documentation was updated.
  • ggWright() plot was updated to more general description.
  • References were updated wintin the app.
