envelope functions combine RSA and AES for encrypting arbitrary sized data.
Other utilities include key generators, hash functions (md5, sha1, sha256,
etc), base64 encoder, a secure random number generator, and @code{bignum} math
methods for manually performing crypto calculations on large multibyte
integers.")

determine whether a set of counts fits a given expected ratio.  To see
whether a set of observed counts fits an expectation, one can examine
all possible outcomes with @code{xmulti()} or a random sample of them
with @code{xmonte()} and find the probability of an observation
deviating from the expectation by at least as much as the observed.
As a measure of deviation from the expected, one can use the
log-likelihood ratio, the multinomial probability, or the classic
chi-square statistic.  A histogram of the test statistic can also be
plotted and compared with the asymptotic curve.")

models, including the bias-reduced linearization estimator introduced by Bell
and McCaffrey (2002)
@url{http://www.statcan.gc.ca/pub/12-001-x/2002002/article/9058-eng.pdf} and
developed further by Pustejovsky and Tipton (2017)
@url{doi:10.1080/07350015.2016.1247004}.  The package includes functions for estimating
the variance- covariance matrix and for testing single- and multiple-
contrast hypotheses based on Wald test statistics.  Tests of single regression
coefficients use Satterthwaite or saddle-point corrections.  Tests of multiple-
contrast hypotheses use an approximation to Hotelling's T-squared distribution.
Methods are provided for a variety of fitted models, including @code{lm()} and
@code{mlm} objects, @code{glm()}, ivreg (from package @code{AER}), @code{plm()}

    (description
     "This package provides meta-analysis methods that correct for publication
bias and outcome reporting bias.  Four methods and a visual tool are currently
included in the package.

@enumerate
@item The p-uniform method as described in van Assen, van Aert, and Wicherts
(2015) @url{doi:10.1037/met0000025} can be used for estimating the average
effect size, testing the null hypothesis of no effect, and testing for
publication bias using only the statistically significant effect sizes of
primary studies.

@item The p-uniform* method as described in van Aert and van Assen (2019)
@url{doi:10.31222/osf.io/zqjr9}.  This method is an extension of the p-uniform
method that allows for estimation of the average effect size and the
between-study variance in a meta-analysis, and uses both the statistically
significant and nonsignificant effect sizes.

@item The hybrid method as described in van Aert and van Assen (2017)
@url{doi:10.3758/s13428-017-0967-6}.  The hybrid method is a meta-analysis
method for combining an original study and replication and while taking into
account statistical significance of the  original study.  The p-uniform and
hybrid method are based on the statistical theory that the distribution of
p-values is uniform conditional on the population effect size.

@item
The fourth method in the package is the Snapshot Bayesian Hybrid Meta-Analysis
Method as described in van Aert and van Assen (2018)
@url{doi:10.1371/journal.pone.0175302}.  This method computes posterior
probabilities for four true effect sizes (no, small, medium, and large) based
on an original study and replication while taking into account publication bias
in the original study.  The method can also be used for computing the required
sample size of the replication akin to power analysis in null hypothesis
significance testing.
@end enumerate

The meta-plot is a visual tool for meta-analysis that
provides information on the primary studies in the meta-analysis, the results
of the meta-analysis, and characteristics of the research on the effect under
study (van Assen and others, 2020).

functions to produce documents using MS Word (or PowerPoint) and functions
to import data from Excel.  Many of the included functions can be found
scattered in other packages and other sources written partly by Titans
of R.  The reason for collecting them here, was primarily to have them
consolidated in ONE instead of dozens of packages (which themselves might
depend on other packages which are not needed at all), and to provide a
common and consistent interface as far as function and arguments naming,
NA handling, recycling rules etc.  are concerned.  Google style guides
were used as naming rules (in absence of convincing alternatives).
The BigCamelCase style was consequently applied to functions borrowed
from contributed R packages as well.")
