DiffXTables 0.99.1

2021-05-14 1. Updated user manuals, README, DESCRIPTION, and the vignette. 2021-04-28 1. Added the citation to the Bioinformatics paper describing Sharma-Song test with observed null table marginals in DESCRIPTION, CITATION, REFERENCES.bib, and README.md files. 2. Introduced a boolean parameter to compensate the issue of Cochran's condition of samples value less than 5 in any cell. 2020-12-24 1. Updated DESCRIPTION 2. Introduced null.table.marginal parameter to use the sharma.song.test with observed and uniform marginal null population. 3. No longer using the correction of normalized frequency table A inside function get.e.mat() 4. Added test cases for the uniform marginal null tables. 5. Added test cases for parameter compensated parameter. 6. Updated the user manual for sharma.song.test() function. 7. Added full citation information and DOI number for the first-order marginal change test ACM paper (Sharma et al, 2020) in DESCRIPTION, CITATION, REFERENCES.bib, and README.md files. 8. stats::chisq.test() is no longer called inside function chisq.test.stat(). This reduce the overhead in chisq.test(), as we only need to compute the Pearson chi-squared test statistic. 2020-12-16 1. Created version 0.1.3 from 0.1.2

2020-08-16 1. Created version 0.1.2 from 0.1.1 2. Fixed a NOTE stating Rdpack package was imported but not used.

2020-08-11 1. Removed DOI from reference (Sharma et al 2020), which is still in press. 2020-08-07 1. Updated DESCRIPTION 2. Updated REFERENCES.bib and CITATION 2020-08-02 1. Updated user manual for type.analysis() function 2. Turned off Yates correction in calculating 2x2 chi-squared statistics in internal R function chisq.test.stat 3. Adjusted test cases for 2x2 tables used for the heterogeneity test without Yates correction. See line 270 and 272 in test_DiffXTables.R 4. Removed duplicate function chisq.test.stat() and created a new file chisq-test-stat.R to include only one copy of the function. 5. Changed the package title to "Pattern Analysis Across Contingency Tables" 2020-08-01 1. Renamed association.order.ana() to type.analysis() 2. Included a S3 method print.DiffXTableTypeAnalysis() 3. Updated the printout of type.analysis() 2020-07-22 1. Added a marginal.change.test for first-order analysis. 2. Added a strength.test for determining the strength of association. 3. Added a association.order.ana method for analysis of strength and change in association. 4. Added test cases for all the methods. 2020-05-14 1. Corrected the normalized frequency table A inside function get.e.mat() in Sharma-Song.R when an entry has both zero row and zero column sums. 2. Add new test cases for the above change. 2020-05-02 1. Created version 0.1.1 from 0.1.0

2020-03-19 1. Changed the return value of the simulator function SimulateDiffXTab(). 2. Renamed the simulator function to simulate_diff_tables() from SimulateDiffXTab(). 3. Minor editing in various files to improve code readability. 4. More tests are added for the simulator function. 5. Corrected typos in the vignette. 2020-03-18 1. Created version 0.1.0 2. Removed unnecessary calculation of the rank of covariance of matrix C, which is theoretically known. Thus the import of Matrix package is removed. 3. Revised function manuals. 4. Changed the simulator function arguments.

2020-01-23 1. Created version 0.0.4 2. A simulator function SimulateDiffXTab() is added.

2019-11-12 1. Updated the package description. 2. Updated the REAMDE.md file. 2019-11-10 1. Updated the vignette. 2. Updated the REAMDE.md file. 2019-10-29 1. Created version 0.0.2. 2. Fixed a bug for 2x2 tables in the Sharma-Song test. A test case is added to check for the bug. 3. Changed package title to "Pattern Heterogeneity via Distributional Differences Across Contingency Tables"
