2023-04-17

  1. Updated document of upsilon()

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) = “Cram9r’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

  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”.
