    o   Use of a different approximation in the calculation of the
	asymptotic variance matrix in vcov that now gives non-zero
	asymptotic covariances.

                 Changes in version 1.2.4 (2015-12-07)                  

    o   Ts.estim() now returns the variance-covariance matrix of the
	regression coefficients.

                 Changes in version 1.2.3 (2014-10-25)                  

    o   Bug fix: Ts.estim() now works correctly when called inside
	another function.

                 Changes in version 1.2.2 (2013-06-11)                  

    o   The rownames of the output matrix r.effects from Ts.estim() now
	identify the clusters.

    o   Test files and some files related to RStudio were removed from
	the source files.

    o   Bug fix: the name of the data file can now be the name of a
	function present in the search path.

    o   A meaningful error message is now returned if the value of a
	covariate in the formula remains constant within all strata of
	at least one cluster.

                 Changes in version 1.2.1 (2012-09-18)                  

    o   Bug fix: Ts.estim() now works correctly with categorical
	covariates.

                  Changes in version 1.2 (2012-07-18)                   

    o   The handling of errors from coxph() has been changed in order
	to identify the cluster from which an error is generated.

    o   The warnings generated by coxph() are now stored in a new
	output value 'coxph.warn'.

    o   A file TwoStepCLogit-Ex.Rout.save has been added to the package
	source in the subdirectory 'tests/Examples'. Now R CMD check
	compares the output from the package examples to this file and
	reports any differences.

    o   The function ddim() has been modified. It nows takes as input
	arguments 'formula' and 'data'. The argument 'formula' must
	identify the response, cluster and strata variables. It has a
	print method. ddim() returns 'Ystat' and 'Sc', which used to be
	returned by Ts.estim(). These elements have been removed from
	Ts.estim() output values.

    o   The print method for objects of class 'Ts.estim' now removes
	from the D matrix the rows and columns containing only zeros
	before printing it.

    o   Tests have been added in the package subdirectory 'inst/tests'.

    o   The extraction of the covariate names for the output has been
	improved.

    o   The package documentation has been updated according to the
	changes mentioned here.

                         Changes in version 1.1                         

    o   Many validation error messages for input arguments have been
	added to Ts.estim().

    o   A function named ddim() has been added. It prints dimension
	statistics for a data set processed with Ts.estim().

    o   The argument 'All.m.1' has been renamed 'all.m.1'.

    o   The output values from Ts.estim() now include 'call', the
	function call.

    o   The output values from Ts.estim() now include 'Ystat', the
	numbers of observations per stratum and the sum of the
	responses per stratum.

    o   The output values from Ts.estim() now include 'Sc', the number
	of strata for each cluster.

    o   The output values 'beta', 'se' and 'D' from Ts.estim() now have
	a 'names' or 'dimnames' attribute in order to identify the
	covariates associated with the coefficients.

    o   A print method has been added for output of the Ts.estim()
	function.

    o   The input argument 'random' of Ts.estim() is now a formula.

    o   The input arguments 'Donnees' and 'Proposed.model' of
	Ts.estim() have, respectively, become 'data' and 'formula', as
	for many functions fitting linear models in R, such as lm().

    o   The package documentation has been updated according to the
	changes mentioned here.

                        Changes in version 1.0-2                        

    o   Tests written with functions from the package 'testthat' have
	been added in the package subdirectory 'inst/tests'.

    o   The output values from Ts.estim() now include 'r.effect', the
	random effect estimates.

    o   'roxygen2' is now used to generate the package documentation.

    o   The examples have been changed in order to reproduce the paper
	results and to avoid warnings.

                        Changes in version 1.0-1                        

    o   Bug fix: Ts.estim() works even if the cluster id numbers are
	not consecutive numbers.

                  Changes in version 1.0 (2011-02-17)                   

    o   First CRAN release of the TwoStepCLogit package.
