vers 0.9:

- Calculation of the power of the traditional chi-square test added;
- Parameter ‘power.alpha’ added to allow the user to set the alpha level used for the power calculation;
- First and last rendered table updated to reflect the added power calculation;
- In the first and last rendered table, the report of the (N-1)/N-corrected chi-square test has been moved up and placed right after the traditional chi-square test, and right before the report of the permuted and Monte Carlo version of the test;
- Same as above for the list of results returned by the function;
- The list of the returned results has been updated to report the power of the traditional chi-square test;
- Default value of the ‘tfs’ parameter reduced to 13;
- Fixes, improvements, and updates to the help documentation.

vers 0.8:

- Permutation-based p-value for the chi-squared statistic added;
- The calculation of the p-value for the permutation-based and Monte Carlo method has been modified from (1+sum(chistat.simulated>=chisq.stat)) / (B+1) to sum(chistat.simulated>=chisq.stat)/B;
- The optional plot of the permutation distribution of the chi-square statistic has been added;
- The option of plotting the permutation and the Monte Carlo distribution side-by-side has been added;
- In the plot showing the distribution of the Monte Carlo chi-squared values, the main and sub title have been amended: reference to “permutation” has been changed to “Monte Carlo”;
- The minimum and the average expected count are now reported in the last rendered table;
- An annotation has been added to the first rendered table in order to give suggestions as to the selection of the most “reliable” chi-square result on the basis of different criteria (following literature; see help documentation);
- In the first rendered output table, the items featuring the annotation at the bottom of the table have been grouped and separated by an empty line to enhance readability;
- Unlike version 0.7, for determining the magnitude of the association expressed by Cadj, Cramer’s V, and V biased-corrected, the coefficients are not internally converted to Cohen’s w, but the Cohen’s thresholds for small, medium, and large effect are dinamically internally computed on the basis of the table’s df;
- For consistency, the indication of the magnitude of the association for the W coefficient is now based on the Cohen’s thresholds, using the same procedure employed for Cadj, Cramer’s V, and V biased-corrected;
- Scholarly literature about the average expected count added to the help documentation;
- Help documentation updated and improved content-wise.

vers 0.7:

- Indication of effect size added to Phi, Phi signed, Phi corrected, Cadjusted;
- Changes and fix in the method underlying the indication of the effect size for Cramer’s V and bias-corrected V; these changes (following Sheskin 2011) allow to provide indication of effect size for tables of any size;
- Wald 95 percent confidence interval around the Monte Carlo (permutation-based) chi-square p-value added;
- The 95 percent CI around the permuted p-value is reported in the
annotations at the bottom of the first produced table, and in the
`Analysis report`

table; - Phi-corrected added;
- W coefficient added (including magnitude of effect size and bootstrap 95% CI);
- W is also reported in the annotation at the bottom of the first tables produced by the function;
- Corrected version of Goodman-Kruskal’s lambda (both aymmetric and asymmetric) added;
- In the annotations at the bottom of the first table produced by the function, Goodman-Kruskal symmetric lambda has been replaced by its corrected version for its ability to addresses skewed or unbalanced marginal probabilities which create problems to the traditional lambda;
- The magnitude of the effect indicated by the odds ratio (introduced
in ver. 0.6) is not returned anymore, but only reported in the
`Analysis report`

table for consistency with other effect size magnitude indication; - Labels used for the magnitude of effect size slightly modified to enhance clarity and consistency;
- The returned results are organised into a nested list format for
better clarity and accessibility:
`input.table`

,`chi.sq.related.results`

,`G.square`

,`residuals`

,`chi.sq.based.assoc.measures`

, and`non.chi.sq.based.assoc.measures`

; - Help documentation updated and improved content-wise;
- An error in the help documentation has been amended: the adjusted chi-square statistic was described as produced by “dividing” the chi-square value by (N-1)/N; “dividing” was meant to read “multiplying”;
- Relevant scholarly references added.

vers 0.6

- chi-square test adjusted by the (N-1)/N correction added;
- magnitude of the effect size as indicated by the odds ratio added;
- help documentation updated, and improved content-wise;
- relevant scholarly references added.

vers 0.5

- the plot of odds ratios is now returned for cross-tabs featuring 2 rows and at least 2 columns;
- to enhance consistency and clarity, the parameter ‘row_category’ has been renamed to ‘row.level’; the parameter ‘reference_level’ has been renamed to ‘reference.level’;
- Haldane-Anscombe correction added in the calculation of odds ratio;
- to improve clarity, minor adjustments have been carried out to the error messages returned when the parameter ‘plot.or’ is ‘TRUE’ but the input cross-tab does not meet the needed requirements (2xk, where k >= 2);
- help documentation updated and improved content- and layout-wise.

vers 0.4

- the facility to plot the odds ratios and 95% confidence intervals for table of size 2xk (where k>2) has been added;
- the above added facility rests on a new internal function (visualize_odds_ratios);
- amendments and updates to the help documentation.

vers 0.3

- Moment-corrected standardized residuals added;
- 95% confidence interval for Cramer’s V added;
- The output version of the input cross-tabulation now reports some essential analytical results in an annotation at the bottom of the table;
- Fix to the output version of the input cross-tabulation when cells feature a frequency of 0;
- The Goodman-Kruskal’s tau reported in previous versions is now indicated as “columns dependent”“, and the”row dependent” version of the same coefficent is now calculated and reported.

vers 0.2

- Relative contributions to the chi-square added;
- Contributions to the chi-square previously reported in ver_0.1 are now called absolute contribution;
- Bibliographical reference added for the abovementioned contributions;
- Significance level of the reported standardized and adjusted standardized residuals can be corrected using the Sidak’s alpha adjustment method;
- G-square test added;
- Symmetric Goodman-Kruskal’s lambda and Goodman-Kruskal’s tau added;
- Cohen’s k (with 95% CI) added;
- Odds ratio (with p value and 95% CI) added (for 2x2 tables);
- Effect size for Cramer’s V and Cramer’s V bias-corrected added to the table of the test’s results; returned for tables with up to 5 degrees of freedom according to Cohen 1988;
- Degrees of freedom added to the output table reporting the test’s result;
- The distribution of the permuted chi-square statistic can be optionally plotted;
- Fix in the calculation of the cells contribution (in percent) to the chi-square;
- Output tables formatted using the ‘gt’ package instead of ‘formattable’;
- Option added to customize the font size of the output tables;
- Improvements to the content and layout of the help documentation.
