Change Log for R-package ic.infer

Version 1.1-7 (04 Oct 2023)
- updated CITATION to newer format
- updated URLs to bht-berlin instead of beuth-hochschule
- removed latin1 encoding
- renamed internal functions orlm.forboot orlm.forboot.fixed to orlm_for... 
  in order to avoid that they are interpreted as S3 methods   

Version 1.1-6 (26 Jan 2018)
- changed % to \% in example code in manual
- changed title to title case
- changed start of description (removed note because of "This package")
- adapted namespace file to current requirements (S3Methods instead of export, 
  importing functions from grDevices, stats and graphics)

Version 1.1-5 (1 August 2014)
- Bug fix (serious bug, thanks to Leonard Vanbrabant for alerting me to this): 
  df calculation in function ic.test was wrong for TP = 11: 
  df were always too large because the length of the parameter vector was used 
  for calculation instead of the number of constraints; 
  this resulted in conservative p-values for TP = 11 in ic.test 
  and consequently also for the overall test in summary.orlm;
  for the latter, the first parameter of the beta distribution was always 0.5 
  too large.
  The bug has been fixed, and notes have been added to the documentation files 
  of functions ic.test and orlm.
- added an explanation to the documentation of pbetabar, 
  explaining which mixture is calculated (different from the expectations that 
  users of likelihood ratio tests in linear models might have; the denominator 
  always adds the error sum of squares from the unrestricted model only, 
  and therefore, the second beta parameter in the mixture is constant)

Version 1.1-4 (13 Sep 2013)
- updated CITATION file
- removed assignment of object bodyfat into global enviroment (file aaa.R)
- moved data files to sysdata.rda instead of data directory
- moved vignette files to vignettes directory
- updated vignette to include the JSS article in the references
- moved packages from Depends to Imports in package description, 
  adapted namespace file to mention all relevant imports; 
  adapted example and test code to access objects from packages no longer 
  attached using :: or require

Version 1.1-3 (18 February 2010)
- makde pdf documentation file into a vignette
- made bodyfat data available in the package (typed them in), 
  i.e. got rid of function bodyfat()

Version 1.1-2 (06 February 2010)
- Removed selective capitalization of output headers
- improved line break properties of output in summary.ict
- added pdf documentation file and ic.infer alias in help
- added citation information

Version 1.1-1 (18 December 2009)
- removed LICENSE file that erroneously claimed a geographical restriction to non-US
  since version 0.8. ic.infer is not and has never been geographically restricted,
  but is subject to GPL >=2.

Version 1.1 (20 November 2009)
- added contrast function contr.diff for increment coding of factors with 
  ordered levels 
- added function make.mon.ui for easier creation of matrix ui in monotonicity situations
- corrected orlm.Rd (quotes in code blocks)
- added two data examples (bodyfat and grades)

Version 1.0-6 (19 September 2008)
Bug fixes:
- orlm and or.relimp did not work properly for linear models on data
  frames without column names.
- bootstrapping did not work on models with factors because of an
  undocumented and unnecessary stopping condition in internal function
  boot.orlm.

Version 1.0-5 (16 August 2008)
- improved error message when using orlm or or.relimp with non-quadratic matrix
- added tests directory for standard automated code testing
- added examples for summary.orest to documentation
- Bug fixes:
  - Fixed typo that made ic.test use asymptotic instead of finite df test, when
    applied to linear model object
  - or.relimp did not work for covariance matrices without column names

Version 1.0-4 (14 August 2008)
- Namespace now exports summary function for class orest (erroneously yielded
  default summary before, although a special method had been added with version
  0.8-2)
- Added helpful error message for plot.orlm, when applied to object that was
  generated based on covariance matrix and therefore without residuals

Version 1.0-1 to 1.0-3 (13 August 2008)
- Prohibit simultaneous occurrence of restriction on intercept and bootstrap
  (consequence of switching to covariance-matrix based calculation in bootstrap)
- Bug fix for internal function orlm_forboot (index – 1 replaced by index in
  call)
- Bug fixes for ic.weights (even and odd sums were wrongly implemented and only
  worked for some numbers of restrictions)

Version 1.0 (12 August 2008)
- ic.weights saves additional time on weight calculation by exploiting that odd and
  even weights each sum to 0.5.
- orlm and or.relimp can now operate based on a covariance matrix only and do
  not necessarily require a linear model for input.
- all.R2 now requests a covariance matrix instead of a linear model for input (it
  should not be necessary for users to directly call all.R2).
- Bootstrapping in orlm is now based on the covariance-matrix-based calculation for
  option fixed=FALSE. Thus, issues are avoided in making bootstrapping work with
  functions that indirectly call lm.
• The documentation has been updated and improved in some respects.
Version 0.8-3 (01 August 2008)
•
