| |
| * betainv.c (gsl_cdf_beta_Pinv): avoid generating a NaN for lx > 0 |
| |
| 2006-04-18 Brian Gough <bjg@network-theory.co.uk> |
| |
| * betainv.c (gsl_cdf_beta_Qinv): fix prototype const |
| |
| 2006-03-07 Brian Gough <bjg@network-theory.co.uk> |
| |
| * poisson.c: added poisson cdf |
| |
| * nbinomial.c: added negative binomial cdf |
| |
| * hypergeometric.c: added hypergeometric cdf |
| |
| * geometric.c: added geometric cdf |
| |
| * binomial.c (gsl_cdf_binomial_Q): added binomial cdf |
| |
| * test.c: added discrete function tests |
| |
| * gamma.c (gsl_cdf_gamma_P, gsl_cdf_gamma_Q): clean up unused |
| code, ensure that branches make P+Q=1 always true |
| |
| * fdistinv.c (gsl_cdf_fdist_Pinv): use P instead of p for consistency |
| |
| * fdist.c (gsl_cdf_fdist_Q): use Q instead of P for consistency |
| |
| * beta.c (gsl_cdf_beta_Q): use Q instead of P for consistency |
| |
| 2006-02-27 Brian Gough <bjg@network-theory.co.uk> |
| |
| * fdistinv.c (gsl_cdf_fdist_Pinv, gsl_cdf_fdist_Qinv): added |
| inverse functions |
| |
| * betainv.c (gsl_cdf_beta_Pinv, gsl_cdf_beta_Qinv): added inverse |
| functions |
| |
| * tdistinv.c (gsl_cdf_tdist_Qinv, gsl_cdf_tdist_Pinv): max 32 |
| iterations, prevent infinite loop |
| |
| * gammainv.c (gsl_cdf_gamma_Qinv, gsl_cdf_gamma_Pinv): max 32 |
| iterations, prevent infinite loop |
| |
| 2005-06-20 Brian Gough <bjg@network-theory.co.uk> |
| |
| * test.c: removed tests using subnormal values, since they tend to |
| fail when extended precision registers are not available. |
| |
| 2004-10-26 Brian Gough <bjg@network-theory.co.uk> |
| |
| * exppow.c: added exppow distribution |
| |
| 2004-10-01 Brian Gough <bjg@network-theory.co.uk> |
| |
| * beta.c (gsl_cdf_beta_P, gsl_cdf_beta_P): return consistent |
| results for out of range values. |
| |
| 2003-08-27 Brian Gough <bjg@network-theory.co.uk> |
| |
| * gauss.c: use parentheses around constant macros to avoid -(-X) |
| being interpreted as --X |
| |
| 2003-07-27 Brian Gough <bjg@network-theory.co.uk> |
| |
| * gumbel1.c (gsl_cdf_gumbel1_Q): use pow in place of exp since |
| compilers seem to handle overflow better in this case (perhaps |
| because it is not an intrinsic function). |
| |
| * gumbel2.c (gsl_cdf_gumbel2_P): handle case of x = 0 explicitly |
| (gsl_cdf_gumbel2_Q): handle case of x = 0 explicitly |
| |
| 2003-07-22 Brian Gough <bjg@network-theory.co.uk> |
| |
| * gamma.c (gsl_cdf_gamma_P): Peizer and Pratt approximation for |
| large a seems to be inaccurate in tails |
| (gsl_cdf_gamma_Q): Peizer and Pratt approximation for large a |
| seems to be inaccurate in tails |
| |
| * test.c (main): added test for large a for gamma |
| |
| * cauchyinv.c (gsl_cdf_cauchy_Qinv): corrected limiting value for |
| Q=1 |
| |
| * added Cumulative Distribution functions from savannah.gnu.org |
