2019-12-18 Søren Højsgaard * Improved doc of dietox. 2019-12-10 Søren Højsgaard * PROTECT / UNPROTECT imbalance fixed * Version 1.3-1 uploaded 2019-12-10 Søren Højsgaard * Migrated to use roxygen * Improved documentation of geeglm * Check for data being sorted by 'id' i geeglm; a warning is issued if not. * QIC added; thanks to Claus Ekstrøm who is now a contributor. * tidy function from broom package is imported. * muscatine data added * Version 1.3-0 uploaded 2014-09-13 Søren Højsgaard * geeglm objects now inherits from lm also (to prevent warning when calling predict). * Version 1.2-1 uploaded 2014-09-13 Søren Højsgaard * Maintainer of geepack is now Søren Højsgaard * Location of vignette fixed * Version 1.2-0 uploaded 2012-01-27 Jun Yan * Commented out #undef NDEBUG in geesubs.cc. * Added a VecPrint function in utils.cc to print DVector; this replaces usage of cerr. 2012-01-09 Jun Yan * Thank Jeffrey Horner and Cole Beck for fixing the undefined symbol error (see 2011-11-14 entry: _Z5ValidIiEN3TNT6VectorIT_EERS3_RNS1_IiEE). The template function "Valid" (in original geesubs.cc) should actually be in the header file. This may fix the compilation error on ubuntu 11.10 too. 2011-11-21 Jun Yan * Added an example to function relRisk. 2011-11-21 Jun Yan * Added an example to function compCoef. * Changed the JSS paper year from 2005 to 2006 in CITATION. 2011-11-16 Jun Yan * Added function relRisk for relative risk regression --- regression for binary response with log link. * Added function relRisk for relative risk regression --- regression for binary response with log link. * Added function compCoef for comparing coefficients of the same sets of covariates between nested models. This implements the method of Yan, Aseltine, and Harel (2011, JEBS); for independent data, the method reduces to Allison (1995, American Journal of Sociology). * Fixed a bug in c++ code in constructing the working covariance structure using the regression model of scale. Simulation tests show improved efficiency in mean parameter estimation when scale regression is present. 2011-11-15 Soren Hojsgaard * Dependence on the doBy package has been removed. 2011-11-14 Jun Yan * Added NAMESPACE for to comply with the requirement of R-2.14.0. * Removed the "assert" lines in utils.cc in order not to crash R, which is quite rude practice. A "-DNDEBUG" has been added to the cppflags in Makevars for a better solution. Due to many asserts in tnt, we cannot get rid of the NOTE message completely: Found ‘_ZSt4cerr’, possibly from ‘std::cerr’ (C++) Found ‘__assert_fail’, possibly from ‘assert’ (C) * Added quote in statements like extract(m, "response") to get rid of NOTE: geese: no visible binding for global variable ‘response’ * Added a line of #undef NDEBUG to the beginning of geesubs.cc; thank Brian Ripley for the NMU. Still unclear why the error without this line: undefined symbol: _Z5ValidIiEN3TNT6VectorIT_EERS3_RNS1_IiEE 2011-02-23 Søren Højsgaard * In geeglm is checked if the model matrix is rank deficient; if so then geeglm exits. Thanks to Jason D Thorpe for pointing this out. * Bug in anova fixed. Thanks to Stefan Boehringer for pointing this out. * Version 1.0-18 uploaded. 2010-01-26 Søren Højsgaard * fixed2Zcor function has been added. This function makes it easier to work with a fixed correlation matrix (in particular when cluster sizes are not equal). * A vignette on models with unequal cluster size, fixed correlation matrices etc. has been added. * Version 1.0-17 uploaded 2008-12-08 Søren Højsgaard * Bugfix in 1.0.15 caused problem in binomial case using cbind(pos,neg). Thanks to Tobias Verbeke. Fixed now. * Bugfix in 1.0.15 caused problem when using variables derived from gam package call to geeglm. Thanks to Eric Rexstad. Fixed now. * Using scale.fix argument gave problem in geeglm. Thanks to Tobias Verbeke. Fixed now. * Fitting large data set with binomial model and 3 measurements per unit using unstructured correlation crashes R. Thanks to Tobias Verbeke. Problem has *NOT* been solved but a remark has been added to doc file. * Version 1.0-16 uploaded 2008-12-01 Søren Højsgaard * When a factor has unused levels, the underlying C code fails. This is now catured in geeglm. Thanks to Janet Young * tests directory added to package * Version 1.0-15 uploaded 2007-07-13 Søren Højsgaard * Smaller 'standardization' changes implemented. Thanks to Achim * Version 1.0-14 uploaded 2007-03-21 Søren Højsgaard * A remark on fixed correlation structures has been added to the geeglm.Rd doc file. * A Wishlist file has been added * Version 1.0-13 uploaded 2007-03-21 Søren Højsgaard * Bug in geeglm fixed so that it now works with a fixed correlation structure. Thanks to Ulrich Halekoh for the fix. 2006-02-13 Jun Yan * Bug in genZcor and genZodds fixed. Thanks to Chongzhi Di . Previously, the matrice generated by genZcor/genZodds are wrong when the number of unique waves is greater than or equal to 10. 2006-01-24 Søren Højsgaard * Bug in anova.geeglm fixed (showed up when there was only one term on the right hand side of ~). * geeglm only works on complete data. This has been pointed out in the man pages. (At some point of time, a proper na.action should be taken). * All datasets are saved as .txt files (previously some were saved as .rda files but that caused problems in building the package on windows xp). 2005-08-13 Jun Yan * The working correlation structure can now be "fixed". 2005-06-13 Søren Højsgaard * Søren Højsgaard has modified the geeglm function so that it can take the 'waves' argument which is used for explicitely specifying the ordering of repeated measurements on the same unit. geeglm can also take the 'zcor' argument for a user defined working correlation structure. * A documentation file for the genZcor function has been added. * All data sets provided are now saved as text files. * ordgee has been modified to check if the response variable is an ordered factor. * geeglm can now take the argument std.err which specifies the type of variance estimate to be calculated. 2005-05-11 Søren Højsgaard * Søren Højsgaard has modified the anova function to make it calculate the correct degrees of freedom. 2005-04-11 Jun Yan * Søren Højsgaard made some minor changes to geeglm - basically, that geese.control did not work. Now it does. 2005-02-09 Jun Yan * Søren Højsgaard joined the development with geeglm, which "works like" glm and returns an object which is similar to a glm object. Residuals and predicted values can be extracted using the generic functions as with a glm object. * An important feature of geeglm, is that an anova method exists for these models.
