Changes in version 0.2.7                        

  - Fix Doxygen update to _PACKAGE issue
  - Fix names in DESCRIPTION
  - Fix "if (class(x) == ...)" issue.

                 Changes in version 0.2.6 (2021-11-16)                  

  - Update to fix M_PI issue with Rcpp update.
  - Fix some non-HTTPS URLs.

                        Changes in version 0.2.5                        

  - Update with DOI for associated paper.
  - Fix an issue with AR(1) and CS covariances. The way these are
    specified means that in case of mis-specification, they may be
    non-monotonic if they are mis-specified and results are near the the
    boundary. The functions were written such that it would not stop in
    this case.

                 Changes in version 0.2.4 (2019-11-14)                  

  - Fixed a minor bug in DF calculation for mixture models.
  - Fixed a minor bug in log likelihood calculation for mixture models.

                 Changes in version 0.2.2 (2019-07-28)                  

  - Added more citations and references.
  - Added reference to the paper this package accompanies.
  - A small series of bug fixes and internal function updates to more
    easily support restrictions on means and variances different
    functions.

                        Changes in version 0.2.1                        

  - Added a number of citations and references to manuals and vignettes,
    including clarifying sources of any other functions.
  - Added logLik functions for LDA, QDA, and MixMatrix objects

                        Changes in version 0.2.0                        

  - Start to add mixture modeling - currently support unconstrained
    variances only and fixed nu parameters for the model = "t" option..
  - Remove list support for matrix LDA and QDA, since they were just a
    pain to support for the predict methods.

                        Changes in version 0.1.0                        

  - Preparing for CRAN submission
  - Add pkgdown (https://gzt.github.io/MixMatrix/)
  - Add ORCID
  - Minor documentation changes
  - Fix nu bug for matrixlda and matrixqda when using normal
    distribution
  - Add vignette for t distribution

                     Changes in version 0.0.0.9949                      

  - changing name to MixMatrix

                     Changes in version 0.0.0.9927                      

  - include EM algorithm (actually an ECME) for estimation of parameters
    of matrix-variate t-distributions
  - include variance specifications for EM for t distribution
  - include the possibility of restricting covariance matrices to a
    correlation structure.

                     Changes in version 0.0.0.9926                      

  - split Wishart functions into CholWishart package
  - migrate some internal functions to RcppArmadillo to improve speed
  - add support for multiple observation input to dmatrixnorm function
  - add support for multiple observation input to dmatrixt and
    dmatrixinvt
  - dmatrix function now have large components in C++
  - add error checking to dmatrixinvt - density only defined when matrix
    is positive definite
  - improve speed of MLmatrixnorm by migrating more to C++ and fixing
    some R bottlenecks

                     Changes in version 0.0.0.9925                      

  - add multivariate digamma
  - add a couple tests for matrixt
  - new plan: add fitting for t-distribution, LDA for t-distribution

                     Changes in version 0.0.0.9924                      

  - Wrote density functions for the Wishart and InvWishart
    distributions. Broke the Wishart functions and mvgamma functions
    into a separate file just for them as they are all related and I may
    break them into their own package.

                     Changes in version 0.0.0.9923                      

  - Rewrote rInvCholWishart to fix a bug where it was not actually a
    Cholesky decomposition - while upper triangular, tcrossprod() was
    InvWishart, not crossprod(). The method is a little slower since it
    involves computing rInvWishart and then taking the Cholesky
    decomposition, but it is faster than doing it in R.

                     Changes in version 0.0.0.9922                      

  - Added LDA and QDA functions with predict() methods. These functions
    are relatively fragile.
  - Marked some functions as internal to clean up the NAMESPACE

                     Changes in version 0.0.0.9921                      

  - Added support for using IID structure for covariance matrices
  - correction on restricted means - only true if known variance

                     Changes in version 0.0.0.9920                      

  - added change to mean estimation to account for restricted means
  - added changes to documentation

                     Changes in version 0.0.0.9919                      

  - Added a NEWS.md file to track changes to the package.
  - Changed the name of the maximum likelihood parameter fitting
    function to MLmatrixnorm since mle.--- could be confused for a
    method.
