Functions to compute quasi variances and associated measures of approximation error.


News

qvcalc 1.0.0

  • Fixed a minor bug in plot.qv()

  • Added an example to the help page for plot.qv, to show how to re-order the points/lines in a call to plot.qv()

qvcalc 0.9-1

  • Reorganised qvcalc as an S3 generic function, to allow others to provide class-specific methods.

  • The package includes method qvcalc.lm for linear and generalized linear models. The back-end computation is now done in qvcalc.default.

  • The method for BTabilities objects is now moved to the BradleyTerry2 package (version 1.0-8). Thanks go to Heather Turner for that.

qvcalc 0.9-0

  • Minor tweaks to fix the dependencies NOTE on CRAN checks

qvcalc 0.8-9

  • Corrects an error in the calculation of the relative errors for simple contrasts. The formula used for this now agrees with the definition of relative error that was given in the Biometrika paper. Many thanks to Shaun Killingbeck for spotting the error in version 0.8-8. Also made some small improvements to examples, and cosmetic changes to avoid a NOTE in the latest CRAN checks.

This history starts with version 0.8-9 (3 February 2015). Earlier versions are not listed here.
