attenuate.d

Measurement error (i.e. the complement of reliability) results in a downward bias
of observed effect sizes. This attenuation can be emulated by this function.

This is a new version of the 'userfriendlyscience' package,
which has grown a bit unwieldy. Therefore, distinct functionalities
are being 'consciously uncoupled' into different packages. This package
contains the general-purpose tools and utilities (see the
'behaviorchange' package, the 'rosetta' package, and the
soon-to-be-released 'scd' package for other functionality), and
is the most direct 'successor' of the original 'userfriendlyscience' package.
For example, this package contains a number of basic functions to create
higher level plots, such as diamond plots, to easily plot sampling
distributions, to generate confidence intervals, to plan study sample sizes
for confidence intervals, and to do some basic operations such as
(dis)attenuate effect size estimates.
