Broadly speaking, the available tools can be divided in two groups: the
probability section and the statistics section. For a quick start, one
could look at their key functions, makeSECdistr and
selm, respectively, and from here explore the rest.
In the probability section, one finds also functions dsn,
dst, dmsn and others alike; these functions
existed also in
The upgrade to
dsn, dst, dmsn and alike fall in
this category: typically, the names of the arguments have been altered, but
they work as before if called with unnamed arguments; similar cases are
msn.mle, sn.cumulants and T.Owen.
Notice, however, that msn.mle and other fitting functions have
effectively been subsumed into the more general fitting function
selm.A second group of functions will work with little or even minimal changes.
Specific examples are functions sn.mle and sn.mle which have
become sn.mple and st.mple, with some additional
arguments (again, one can achieve the same result via selm) and
dp.to.cp, which has been replaced by the more general function
dp2cp.
Finally, some functions are not there any longer, with no similarly-working functions in the new version. The more prominent set of cases is represented by the functions for computing profile log-likelihoods. There is a long-term plan to re-instate similar facilities, possibly in a more flexible form, but not in the near future.
