Updated document of upsilon() Changes in version 0.0.4.3 2023-04-09 1. Added if in upsilon.R 2023-04-06 1. Added upsilon() function condition in "upsilon_cpp.cpp" 2023-04-04 1. Added avg = n/(nrnc). Changed n/(nrnc) to "avg" and move "avg" outside of sum. From dividing by "avg" each time to dividing by "avg" only once when computing statistics. 2023-04-02 1. Fixed Warning message: In n * nr * nc : NAs produced by integer overflow in "upsilon.test.R" 2. Changed some codes to make the layout more concise and beautiful in "upsilon.test.R", "upsilon.gof.test.R", "modified.chisq.test.R", and "modified.GTest.R". 3. Added the following line // [[Rcpp::interfaces(r, cpp)]] in "modified_chisq_statistic_cpp.cpp" and "upsilon_gof_statistic_cpp.cpp". 4. Switched row-by-row to column-by-column traverse in modified_chisq_statistic_cpp(). 5. Changed line 64 names(ESTIMATE) = "Cramér's V" to names(ESTIMATE) = "Cram\uE9r's V" in "modified.chisq.test.R" 2023-03-23 1. The upsilon_statistic_cpp() has been optimized to speed up by a factor of two. In traversing an Rcpp NumericMatrix, accessing elements column wise can be much faster than row wise. We saw 2 times speedup on 10,000x10,000 matrix after we switched row-by-row to column-by-column traverse. 2023-03-09 1. Added the following line // [[Rcpp::interfaces(r, cpp)]] in "upsilon_statistic_cpp.cpp" to export the upsilon_statistic_cpp() C++ function to other packages. 2023-02-28 1. Added conclusions in Table 7（according to the author）in vignette "upsilon_test.Rmd". 2023-02-22 1. Added legend for stars_pval() in vignette "upsilon_test.Rmd". 2. Interpreted the conclusions in Table 7. 3. Placed the tables(1-5) below the description. 2023-02-20 1. Added test cases using testthat (requested 2023-02-18) 2. Deleted the "doc" folder, which seems to contain another old copy of the vignette. (requested 2023-02-18) 3. Revised the note under 2023-02-14. (requested 2023-02-19) 2023-02-19 1. Updated the vignette "NEWS.md" 2. Updated DESCRIPTION, REFERENCES.bib. 3. Updated R manual inside "upsilon.test.R" 2023-02-18 1. Updated the vignette "upsilon_test.Rmd" 2. Updated DESCRIPTION, REFERENCES.bib. 3. Updated the R manual for all R functions. 2023-02-14 1. Effect size changed (From (Upsilon statistic/max Upsilon statistic) to sqrt(Upsilon statistic/max Upsilon statistic)). The reason for taking the square root is to normalize the Upsilon statistic so that it falls between 0 and 1, which makes it easier to interpret the strength of the association between the variables. When the except value are all same in a 2x2 table, the Upsilon statistic is as same as Pearson's chisq-test, the effect size is also same. 2. Added Table 6 and Table 7 in vignette "upsilon_test.Rmd". 2023-02-07 1. Added comparisons with Fisher’s exact test in vignette "upsilon_test.Rmd". 2023-02-02 1. Removed compare.results from vignettes. Changes in version 0.0.4.2 2022-07-01 1. Corrected the residual matrix calculation for the upsilon.test(). 2022-06-29 1. Added effect size as the estimate in the return of the Upsilon test. MS. 2022-06-16 1. Created version 0.0.4.2 from 0.0.4.1. 2. Renamed statistic.cpp() to upsilon.statistic(). (Requested 2022-06-16) 3. Added function modified.chisq.statistic(). (Requested 2022-06-16) Changes in version 0.0.4.1 2022-06-16 1. Changed the return of statistic.cpp() and gof.statistic.cpp() from a list to a numeric. 2. Updated the tests due to the changes in 1. 2022-06-15 1. Created version 0.0.4.1 2. For the modified.chisq.test function changed the estimate to be the Cramer's V. The current implementation is V^2. (Requested 2022-06-01) 3. Moved the comparison with other methods to vignettes (compare.results.R, auc.plot ) (Requested 2022-06-08) 4. Moved the non-essential packages in the "Imports:" field to "Suggests:" field in DESCRIPTION. (Requested 2022-06-08) 5. Deleted "test.cpp" from the src folder. (Requested 2022-06-08) Changes in version 0.0.4 2022-04-06 1. Created version 0.0.4. Changes in version 0.0.3 2022-01-06 1. Created version 0.0.3. Changes in version 0.0.2 2021-12-23 1.
