In phargarten2/matrixNormal: The Matrix Normal Distribution

matrixNormal 0.1.0 2021-Dec-29

• pmatnorm: Included argument keepAttr to pass to mvtnorm::pmvnorm() v.1.1-2: logical allowing users to attach error and message to the return value.

• rmatnorm:

• Added argument checkSymmetry = FALSE to mvtnorm::rmvnorm() as the matrices are already checked for symmetry.

• U and V are incorrectly switched, (thanks, @prockenschaub, https://github.com/phargarten2/matrixNormal/issues/1)

  • Added warning to earlier versions of R
  • Changed reference cited.
  • Made argument method clearer

• Documentation clarification, thanks @1

• Vignette clarification, thanks @#1.

matrixNormal 0.0.5 2021-Apr-1

Bug Fixes

• Minor Change: Changed lazy data to FALSE in description file to remove notes on CRAN check in R 4.0.5.

matrixNormal 0.0.4 2020-08-26

• New vech() function: performs half-vectorization on a symmetric matrix. This is the vector-form of the lower triangular matrix only. Unlike other functions on CRAN, vech() inherits any names from the matrix.

Bug Fixes

• dmatrixnorm: Clarified by replacing the name of argument use.log with log for consistency in argument name with mvtnorm and stats package.
• is.symmetric(), is.positive.definite(), is.positive.semi.definite():
  • if A is not symmetric, these functions NOW return FALSE instead of stopping the function. Restructured helper find.eval().
  • if A contains a missing value (NA), these functions NOW return NA.
• rmatrixnorm: Added the first argument s to draw many random samples. Only 1 sample is still drawn; the argument currently has no effect but acts as a placeholder in future releases.
• Clarified documentation.
• Added session information and version details to the vignette. The updated versions of the packages listed do not affect the results of matrixNormal functions.

matrixNormal 0.0.2 2019-12-5

• The documentation is clarified.
• Submitted to CRAN but failed to be released.

matrixNormal 0.0.1 2019-07-09

• Vignette is added, replacing the package R file. Included the use and uniqueness of matrixNormal distribution. Also included an example that uses the package. Added additional packages to be imported in Documentation.
• Documentation clarified.
• Minor Changes in Examples: Changed order of examples in rmatnorm() for reproducibility Made clearer in using the dataset package in pmatnorm() example ** Removed installation of matrixcalc package in is.symmetric.matrix examples.
• is.positive.definite(), is.positive.semi.definite() returns NA if the matrix contains missing value (bug fix).
• pmatnorm(), dmatnorm(), rmatnorm() now throws error if the parameters of the matrix Normal Distribution M, U, or V contain any missing values.
• rmatnorm() now returns a matrix with rownames from U and the colnames from V.
• In rmatnorm(), pre0.9_9994 that was passed from rmvnorm() function in mvtnorm library is removed, because it is not needed. This argument was introduced in mvtnorm library to fix a bug in version 0.9-9993, but matrixNormal uses a version of at least 1.0.8. This argument is just not needed, and if pre0.9_9994 is set to TRUE, nothing will happen.

matrixNormal 0.0.0.9000

• This is a new submission.
• Added a NEWS.md file to track changes to the package.
• First Release of the Package
• Successfully passed windows check.
