Changes in version 1.1.6 (2016-11-07)
o Added a helper function to obtain
score residuals from clogit
given the estimated coefficients,
the observed outcomes,
the design matrix
and the id vector.
o Fixed a bug when using retrospective
conditional logistic regression
o Add doubly robust estimation in
conditional logistic models
Changes in version 1.1.5 (2016-04-25)
o Bugfixes
Changes in version 1.1.4 (2016-01-13)
o In some data manipulation steps, the data.table
package is used to obtain better speed.
o For estimation in conditional logistic models
only outcome-discordant clusters are used
o Calculation of residuals for estimating equations
for conditional logistic models implemented in C++
using the Rcpp and RcppArmadillo packages.
o Drops unused levels for factor variables
Changes in version 1.1.3 (2015-06-23)
o Fixed a bug in 'drgeeData' which caused an error
when one of the nuisance models only contained an
intercept
Changes in version 1.1.2 (2015-05-18)
o Fixed a bug in 'drgeeData' for the 'estimation.method'
which happened when 'cond = TRUE' and 'olink = "logit"'.
Changes in version 1.1.1 (2015-05-09)
o Fixed a bug in 'drgeeData' that caused error when
no data argument is supplied.
o There was an error in the previous version, when
the function 'drgeeData' removed outcome concordant
cluster for conditional methods. This is now corrected
such that this only happens for conditional logistic
methods.
Changes in version 1.1.0 (2015-04-20)
o The arguments 'outcome', 'exposure' and 'clusterid'
can be supplied as vectors or as a string.
o Changed the interface for the 'drgee' function.
Now the argument 'estimationMethod' has to be
"dr","o", or "e" corresponding to previous choices
"dr", "obe" and "ebe".
When 'estimationMethod="o"', the user can supply an
argument 'exposure' instead of 'emodel'. Similarly,
when 'estimationMethod="e"', the user can supply an
argument 'outcome' instead of 'omodel'.
o Changed the functions 'drgee' and 'gee' such
that they always return the variance as a matrix.
o Added a function 'gee' which calculates all
coefficients in a regression.
o Added an option 'cond' for 'drgee' and 'gee' for
models with cluster-specific intercepts.
Changes in version 1.0.1 (2014-01-27)
o Fixed a bug in 'drFit'. The calculation of the
Jacobian was incorrect for doubly robust estimation
with outcome link logit, resulting in inconsistent
estimates of standard errors. This bug is now fixed.
Changes in Version 1.0 (2013-12-19)
o First version released on CRAN
