ASA109, a C library which "inverts" the incomplete Beta function by Cran, Martin and Thomas.
Given a value of the incomplete Beta function, it can determine the argument that produced that value.
ASA109 is Applied Statistics Algorithm 109. Source code for many Applied Statistics Algorithms is available through STATLIB.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
ASA109 is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
ASA063, a C library which evaluates the incomplete Beta function.
ASA226, a C library which evaluates the CDF of the noncentral Beta distribution.
ASA310, a C library which computes the CDF of the noncentral Beta distribution.
BETA_NC, a C library which evaluates the CDF of the noncentral Beta distribution.
TEST_VALUES, a C library which stores a few values of various mathematical functions.
TOMS179, a C library which evaluates the incomplete Beta function.
Original FORTRAN77 version by GW Cran, KJ Martin, GE Thomas; C version by John Burkardt.
