Fixed issue 6061 raised by William Scott, who also supplied examples.
The quantile function,
qsnorm, was wrong around
0.5. The error was in
.qsnorm. For now its version before
the fix is kept as
.qsnorm_orig. Basically, branching was
p = 0.5, which is correct only for the symmetric
\xi = 1, and should be
1/(1+\xi^2) instead. More
details in the source code. The error was affecting the central
part of the distrbution with the interval becoming larger for
\xi further away from 1.
psnorm, had an error at a single point,
coinciding with the wrong value for
p = 0.5 returned by
qsnorm(0.5) before the fix. The result was that
psnorm(qsnorm(0.5)) was returning 0.5, falsely giving
qsnorm(0.5) was correct.
Not mentioned in issue 6061 but the same problems held for
the other skewed distributions:
psged. The original versions of the relevant
internal functions are kept for now with a suffix
Edited the documentation of
garchSim. It was somewhat incomplete and contained
leftovers, apparently from old versions of the functions.
Documented the datasets. Previously the help page for them was a placeholder, without the names of the available datasets. There is no information about the time span of the data or how the returns were calculated.
This is a CRAN release of version 4001.1, with trivial changes in ‘DESCRIPTION’.

This may require updates in your code, e.g., adding
as it has been done in our own fGarch's examples and tests.
.gogarchFit() is at least mentioned in the documentation.
Added registration of compiled functionality for speed up and as good practice.
Depends: entries and checked exactly which
parts of packages, notably fBasics, timeDate, and
timeSeries, are needed and imported only these.
Eliminated warning about 'length > 1' character formula in
Replaced the error-prone checking for 'class()' equality by 'inherits(*, <class>)'.
Exporting practically everything seems “wrong” (according to MM):
.<some> functions have no documentation and
hence should either be (renamed and) documented or no longer be exported.
