// DESCRIPTION:
|
|
// ~~~~~~~~~~~~
|
|
//
|
|
// This file tests the incomplete beta function inverses
|
|
// ibeta_inv and ibetac_inv. There are three sets of tests:
|
|
// 1) Spot tests which compare our results with selected values
|
|
// computed using the online special function calculator at
|
|
// functions.wolfram.com,
|
|
// 2) TODO!!!! Accuracy tests use values generated with NTL::RR at
|
|
// 1000-bit precision and our generic versions of these functions.
|
|
// 3) Round trip sanity checks, use the test data for the forward
|
|
// functions, and verify that we can get (approximately) back
|
|
// where we started.
|
|
//
|
|
// Note that when this file is first run on a new platform many of
|
|
// these tests will fail: the default accuracy is 1 epsilon which
|
|
// is too tight for most platforms. In this situation you will
|
|
// need to cast a human eye over the error rates reported and make
|
|
// a judgement as to whether they are acceptable. Either way please
|
|
// report the results to the Boost mailing list. Acceptable rates of
|
|
// error are marked up below as a series of regular expressions that
|
|
// identify the compiler/stdlib/platform/data-type/test-data/test-function
|
|
// along with the maximum expected peek and RMS mean errors for that
|
|
// test.
|
|
//
|
|
|
|
void expected_results()
|
|
{
|
|
//
|
|
// Define the max and mean errors expected for
|
|
// various compilers and platforms.
|
|
//
|
|
// Note that permitted max errors are really pretty high
|
|
// at around 10000eps. The reason for this is that even
|
|
// if the forward function is off by 1eps, it's enough to
|
|
// throw out the inverse by ~7000eps. In other words the
|
|
// forward function may flatline, so that many x-values
|
|
// all map to about the same p. Trying to invert in this
|
|
// region is almost futile.
