The ERF implementation uses the rational approximation, interval structure
and published coefficients of W. J. Cody's CALERF algorithm:

CALERF routine itself is not distributed with this project.

Native pbivnorm component
-------------------------

The file src/main/fortran/pbivnorm.f is derived from the CRAN pbivnorm package
version 0.6.0:

    https://CRAN.R-project.org/package=pbivnorm
    https://github.com/brentonk/pbivnorm

The numerical Fortran code is attributed to Alan Genz. The vectorized
PBIVNORM subroutine was added by Brenton Kenkel in 2011 and was based on a
similar interface by Adelchi Azzalini in the mnormt package. Additional authors
are identified in the comments retained in the source file.

The CRAN pbivnorm package is licensed under GPL version 2 or any later version
(SPDX: GPL-2.0-or-later). Native binaries bundled with or built by this project
are compiled from that source and carry the same license.

Distributions combining the Java component and pbivnorm are provided under
GPL-3.0-or-later. Complete license texts are available in LICENSES/ and, in
built JAR files, META-INF/LICENSES/.
