pdqr 0.2.1 2019-12-15

  • Outputs of new_p() and new_q() now work more accurately in case of dirac-like functions.
  • form_mix() now uses new algorithm of discontinuity approximation, which enables proper handling of distributions with “touching” supports.
  • New boolean option “pdqr.assert_args” may be used to turn off sanity checks of function arguments, which will somewhat increase general execution speed.
  • Minor fixes to remove CRAN “additional issues”.

pdqr 0.2.0 2019-11-06

  • form_estimate() gets argument estimate renamed to stat to avoid possibly confusing word duplication.
  • form_retype() gets default value NULL of type, which means taking opposite of input’s type. This usage seems to be the most common.
  • form_retype() gets new default method “value” that preserves ratio of d-function values at certain “x” points. It is more robust than previous options.
  • summ_spread() gets new method “range” with corresponding new summ_range() function. It returns a range length of “x” values within region of positive probability.
  • New functions form_recenter() and form_respread() are implemented. They change center and spread of distribution (with linear transformation) to be equal to some desired value.
