MVT
package contains a set of routines to
perform estimation and inference under the multivariate t-distribution. These methods are
a direct generalization of the multivariate inference under the gaussian assumption. In
addition, these procedures provide robust methods useful against outliers. The package uses
these functions in algorithms to simulate, analyze, and fit the model to data. The methodology
is described, with examples, in the following paper.
Please report any bugs/suggestions/improvements to Felipe Osorio, Universidad Técnica Federico Santa María. If you find these routines useful or not then please let me know. Also, acknowledgement of the use of the routines is appreciated.
Latest binaries and sources for MVT are available from CRAN package repository .
To install this package, start R and enter:
Alternatively, you can download the source as a tarball or as a zip file. Unpack the tarball or zipfile (thereby creating a directory named, MVT) and install the package source by executing (at the console prompt)
Next, you can load the package by using the command: library(MVT)
