The attribute

`nobs`

has been added to the object returned from`adjust_loglik()`

and as an attribute to the object returned from`logLik.chandwich()`

.In

`compare_models()`

the parameter names (if any) are passed to the (adjusted) loglikelihod function, in case they are required inside the loglikelihood function.There was a bug in the plot method for objects of class “confreg” returned from conf_region(): if the parameters had not been named by the user then ? appeared twice in the console, requiring the user to press return twice before the plot as produced. This has been corrected.

`adjust_loglik`

has an additional arguments`mle`

,`H`

and`V`

that allow the user the option to supply the MLE, the Hessian of the independence loglikelihood (H) and the variance of the vector of cluster-specific contributions to the score vector (V), each evaluated at the MLE, rather than estimating these within`adjust_loglik`

.An anova S3 method for class “chandwich” has been added. This compares two or more nested models using adjusted likelihood ratio tests of successive pairs of models, using

`compare_models()`

.A confint S3 method for class “chandwich” has been added. This is based on a fairly trivial call to

`conf_intervals()`

.S3 methods

`coef`

,`vcov`

and`logLik`

for class “chandwich” have been added.

A bug in

`compare_models()`

has been fixed. The bug resulted an error in cases where the argument`larger`

corresponded to a simplication of the full model in which element i of the parameter was fixed but some element i+n, for n > 0, was not fixed.Estimated unadjusted (VC) and adjusted (adjVC) variance-covariance matrices of the free model parameters are now available in the object returned by

`adjust_loglik()`

.The documentation of the argument

`approx`

to`compare_models()`

has been edited to make it clearer that if`smaller`

is not supplied then`approx = FALSE`

will be used regardless of any value supplied for`approx`

in the call to`compare_models()`

.If parameter names are supplied to

`adjust_loglik()`

(via`par_names`

) but`fixed_pars`

is numeric then the names of the parameters in`fixed_pars`

are now also inferred in the case where a larger model is not supplied via`larger`

. This means that the output from`compare_models()`

will now use the parameter name, rather than the parameter number.If a numeric

`fixed_pars`

is supplied to`compare_models()`

then the names of the parameters in`fixed_pars`

are inferred, if they are available in the supplied object`larger`

.The summary method for class “evpost” is now set up according to Section 8.1 of the R FAQ at (https://cran.r-project.org/doc/FAQ/R-FAQ.html).

In the Introducing chandwich vignette a typo in the definition of HA has been corrected. The expression given is for the inverse of HA, not for HA.
