DPQmpfr News

Version 0.3-3 (2024-08-19, svn r327)

NEW FEATURES

• stirlerrSer(n, k) now allows k <= 22.

• add some ⁠\link[<pkg>]{..}⁠ as now required.

• dtWVm() is an “mpfr-ized” version of DPQ's dtWV().

• gam1M(), lgamma1pM(), and algdivM() each generalize the corresponding function in package DPQ for the use with Rmpfr's "mpfr" numbers, notably avoiding cancellation by adding additional precision bits.

• New pbeta_bpser() using the 3 auxiliary functions for an mpfr-ized version of R's pbeta().

• More non-central t probability computations .. unfinished currently

Misc

• internal dpoisEr(), gets arg log2.min, back to previous (2020) value, such that "correct underflow" in R does not give rel.err of -1.

DEPRECATED AND DEFUNCT

• dntJKBm() is deprecated, as DPQ's dntJKBf() works already perfectly “mpfr-ized”.

Version 0.3-2 (2023-12-05, svn r281)

NEW FEATURES

• utility functions for testing dpois_raw() etc, notably for package DPQ.

• new “mpfr-ized” pnormAsymp() and qnormAsymp()

• new ldexp(f, E) utility.

Misc

• URLs in ‘DESCRIPTION’

Version 0.3-1 (2021-05-17, svn r174)

NEW FEATURES

• stirlerrM(n) and stirlerrSer(n,k) providing Stirling's formula approximation errors for bigrational ("bigz") or "mpfr" numbers.

Version 0.3-0 (2020-11-23, svn r156)

NEW FEATURES

• dhyperQ(), phyperQ(), and phyperQall() for exact hypergeometric probabilities (as “big rational”s, i.e., gmp package's "bigq").

• Finally export (and add to svn!) dbetaD94(), pbetaD94(), and qbetaD94().

  Add log_scale option to both pbeta*() and qbeta*().

• “mpfr-ize” more, notably pnorm*() from DPQ (0.4-2).

Version 0.2-0 (2018-08-16, svn r40)

FEATURES

• Split off from original DPQ package. This DPQmpfr package will explicitly depend on both CRAN R packages gmp and Rmpfr.

• Started with a MPFR-ized version of DPQ's dnt() function for the non-central t-distribution density.
