News

Changes in version 0.9-6.1

  • had "fake" vignette, so removed .Rnw file. Now just pdf files in the /inst/doc/ directory.

Changes in version 0.9-6.0

  • Changed /inst/News.Rd to NEWS
  • changed help, no longer says it does Cox regression
  • modified mgee function so that if calls the gee function then geeUOmega. The previous method was clunky since it basically copied the code from gee and added some lines. Now I do it a better way by calling the gee function, then using it as an argument in the newly created geeUOmega function which inputs the output from gee. Changed help accordingly.

Changes in version 0.9-5.3

  • Changed print.saws file. It had an error when the test matrix was not p X p (where p=number of coefficients).

  • Removed dependence on survival. I hope to put adjustment for Cox proportional hazards in the future, but have not done it yet, so there is no dependence.

Changes in version 0.9-3.3

  • fix bug when the number of parameters is 1 (see dfCalc.R).
