CAISEr 1.0.16 Unreleased

  • Maintenance update:
    • minor fix in se_boot() to remove CRAN warning.

CAISEr 1.0.15 2019-08-19

  • Maintenance update:
    • minor fix in imported packages to remove NOTE in CRAN checks.
    • Updated DESCRIPTION with links to published work.

CAISEr 1.0.14 2019-08-02

  • CAISEr plotting now returns a list of ggplot objects and relevant dataframes, and plots a nested plot of relevant information.
  • fixed bug when running experiment with two algorithms (due to the default drop = TRUE when subsetting rows in se_param()/se_boot()).

CAISEr 1.0.6 Unreleased

  • Added plot function to class CAISEr

CAISEr 1.0.5 2019-07-13

  • Major update: package can now deal with comparisons of multiple (>2) algorithms. This version is not backward compatible with versions 0.xx. To use the previous versions (e.g., to replicate the results from the paper “Sample Size Estimation for Power and Accuracy in the Experimental Comparison of Algorithms”, Journal of Heuristics 2019), install the previous version from
  • Replaced function calc_nreps2() by calc_nreps() to calculate the number of repetitions in the case of multiple (>2) algorithms.
  • function calc_se() now performs point estimate and standard error calculations for all pairs of interest in the case of multiple algorithms.
  • function calc_instances() now returns the number of required instances to maintain the desired power for the family of experiments, based on Holm’s step-down correction. It also returns the sequence of alpha values and the corresponding power to detect the effect size d, for each comparison using Holm’s method.
  • Removed class CAISER_powercurve and all associated methods (print, summary, plot) as these were (very) rarely used.
  • Added class nreps with new summary/plotting functions.
  • Updated print and summary methods.
  • The package now supports saving and (re)loading partially executed experiments.

CAISEr 0.3.3 2018-07-24

  • fixed problem with printing version in the vignette.

CAISEr 0.3.2 Unreleased

  • fixed rare bug in calc_se() that resulted in NaN if two vectors with the same sample mean and same sample variance were passed as arguments.

CAISEr 0.3.1 Unreleased

  • Added function to consolidate partial results saved to file (consolidate.partial.results())
  • Minor improvements to saving partial results to file: users can now select arbitrary directory for saving

CAISEr 0.3 Unreleased

CAISEr 0.2.4 Unreleased

CAISEr 0.2.3 Unreleased

  • Improved plot and summary functions for CAISErPowercurve objects.
  • Added options to calc_power_curve() to determine the range of effect sizes to consider.

CAISEr 0.2.2 Unreleased

  • Added new example and use case to calc_nreps2()

CAISEr 0.2.1 2017-10-29

  • Minor fixes, particularly in printing function.

CAISEr 0.2.0 Unreleased

  • Initial release on CRAN.
