ROIstat Changelog

Review changes to the app over time:

  • v1.2 2021/12/08
    • In order to fix a bug with single-column data not working with dynamic filtering, load a fresh RStudio instance and type:
      • remotes::install_github("dreamRs/datamods")
    • Fixed a bug with Mean and Dispersion Tests, Enter Statistics where it would not allow the user to choose between the Welch and Fisher t-tests
    • Fixed a bug with Mean and Dispersion Tests, Use Data, data in columns where it would not allow the user to choose between the Welch and Fisher t-tests
      • Also added some additional confidence intervals for the latter
    • Added control chart limit calculations using various statistics for
      • X-bar
      • X
      • Range
      • Standard deviation
      • Variance
      • p (exact binomial and approximate)
      • np (exact binomial and approximate)
      • c (exact Poisson and approximate)
      • u (exact Poisson and approximate)
  • v1.1.1 2021/11/17
    • Fixed a bug in oneway post-hocs that broke the output if there were multiple columns beyond the factor and data. The new code should be robust to this.
  • v1.1 2021/11/12
    • Added ability to draw one or two tails on binomial, Poisson, and exponential and get the area inside or outside of those tails
    • Added some color to oneway ANOVA post-hoc graphs
    • Added note on oneway ANOVA post-hoc graphs for fixed and Kruskal-Wallis to indicate that the points are means and medians respectively
    • Added exact one-sample Poisson sample size and power calculations
    • Added approximate two-sample Poisson sample size and power calculations
    • Changed bandwidth on violin plots for ANOVA to type SJ to match EDA density plots
    • Cleaned up the output tables for distributions, added an option to show or hide the table for Poisson and Binomial
  • v1.0 2021/11/02
    • First full public release
    • Added skewness and kurtosis in EDA descriptive statistics
    • Fixed a bug in the Natural Tolerance calculations when using data
    • Reworked UI in mean and dispersion tests to be more consistent with other UI elements in the app
    • Fixed a bug that caused some people to experience "argument is missing with no default" error
    • Fixed a bug with oneway random effects plot not using the selected color palette and non-rounded data
    • Added the ability to either auto select normality tests or manually select them
    • When doing a two-sample independent t-test, added the ability to select Welch (recommended), Fisher, or auto select based on variance test
    • Added McNemar's Test of Change to Two-Sample Dependent tests
    • Added Cohen's kappa to Correlation and Association - Enter Statistics for a quick way to get κ
  • v0.85 2021/10/28
    • Added post-hoc analysis for fixed effect ANOVA
      • Plot of levels with points for the means, connecting lines, violin or boxplot
      • Tukey's HSD results table along with detailed results for each test
    • Added post-hoc analysis for random effect ANOVA
      • Plot of the random effect magnitude compared to the population so you can see what might be possible by reducing the random effect
      • Includes a confidence interval for the interclass-correlation coefficient
    • Added post-hoc analysis for Kruskal-Wallis rank order ANOVA
      • Plot of levels with points for the means, connecting lines, violin or boxplot
      • All-pairwise comparisons using the Mann-Whitney U test, error controlled by Bonferroni-Dunn
        • Each U test p-value is multiplied by the number of tests (with a maximum of 1), so compare the p-value as reported to the desired family-wise alpha
    • Various bug fixes
  • v0.84 2021/10/22
    • Added a oneway ANOVA for fixed and random effects including dispersion test and correct importance calculations
    • Added Kruskal-Wallace oneway ANOVA by ranks
    • Fixed bug in sample sizes that led to incorrect calculations when "less than" was selected
      • That fix cascaded multiple bugs that led to incorrect beta calculations and labeling when "less than" was selected, fixed
    • Fixed minor formatting issue with sample size output
    • Fixed a bug with reference type data in nonparametrics that resulted in an error "object x2 not found"
  • v0.83 2021/10/13
    • Fixed bug in sample size calculations - now allows you to test for the alternative being equal, lesser, or greater than the null
    • Added confidence intervals and natural tolerances for column and factor data
    • Added many selectable descriptive statistics for column and factor data
    • Added common and custom quantiles for column and factor data
    • Added scatterplots with various regression models, including confidence intervals and significance test
    • Added new requirement - ggplot2
    • Added new requirement - propagate (forked)
    • Need to update
      • lolcat
      • datamods
  • v0.82 2021/09/28
    • Added the ability to choose different color palettes. These palettes have similar luminance and are to one degree or another colorblind-safe
    • Added histograms, frequency polygons, and density plots for column and reference data with normal curves and spec limit options. Column data can be overlayed on the same axis.
    • Added boxplots for column and reference data
    • Adjusted CSS for output tables to make them more compact
    • Added variable name for normality tests for factor type data
    • Various minor bugfixes
    • Fixed bug that broke the UI for factors used in the two-way independent t-test where there were more than two categories for the factor
    • KNOWN ISSUE
      • If the imported data has NA for one of the vectors and you try to use that column and one without NAs in the normality tests, you will get an error.
    • WORKAROUND
      • You can assess the normality of the data with NAs by itself
  • v0.81 2021/09/09
    • Added the ability to use one or more columns as factors for normality testing
    • Added the two-sample independent z-test for data via calculations
    • Normality test p-values are now highlighted in grey if p > α and in yellow if p < α
    • Added the ability to choose a factor and data column for:
      • Normality testing
      • Independent two-sample mean and dispersion tests
      • Independent two-sample nonparametric tests
    • Various minor bugfixes
    • Fixed "data labels don't change if updated and then new data loaded" bug
    • Fixed the "correlations don't show until one with a crosstab is selected"
  • v0.71 (unreleased)
    • Moved "one sample test for variance" checkbox for the data and non-data mean and dispersion tabs
  • v0.7 2021/08/25
    • First public alpha release
