There are two popular variants of the Holt-Winters forecasting method; RRDtool
supports the "additive" method, which means that seasonal variation is simply
added to the baseline. For our application, it would be more appropriate to use
the "multiplicative" Holt-Winters method, where seasonal variation is a
coefficient multiplied by the baseline. Quick example to illustrate the
difference: if the average doubles season-over-season, the additive method
would predict the delta between min and max to be constant, whereas the
multiplicative method would predict the delta to double as well.
Attached is a patch against trunk to support the multiplicative method. I've
done this with a new consolidation function, MHWPREDICT, which is essentially
interchangeable with HWPREDICT. There is a noticeable improvement in prediction
deviations for certain types of functions; the attachments show HWPREDICT and
MHWPREDICT predictions for a function with an x*sin(x) component.
Because HWPREDICT and MHWPREDICT differ only in their equations, I've factored
out their math into rrd_hw_math.c. The appropriate smoothing functions are
passed to the update functions in a container of function pointers, which are
called where appropriate. Thus the additive and multiplicative methods use the
same update functions, and the right equations are evaluated without having
flag checks everywhere. This approach, I think, makes the algorithms quite
clear, with minimal duplicate code.
I have moved update_hwpredict, update_seasonal, update_devpredict,
update_devseasonal, and update_failures into a separate file, rrd_hw_update.c,
with some slight refactoring related to rrd_hw_math.c. I ran some
regression tests against trunk to make sure I didn't break anything with
the existing HWPREDICT code.
MHWPREDICT uses the same deviation smoothing and failure detection algorithms
as HWPREDICT.
Some helpful references on the multiplicative Holt-Winters method:

http://ideas.repec.org/p/msh/ebswps/1999-1.html (paper on variations to the
multiplicative Holt-Winters, including variance calculations; FYI, my
implementation uses "Model 1")
My employer and the owner of this patch (IMVU, Inc.) is happy to license it
under the same terms as RRDtool, i.e. give it to the project.

- flag rrd_resize's old file with RRD_COPY

comments
- rrd_close(): implement printing mincore results for the rrd if

- rrd_open(): madvise start addresses need to be page-aligned; implement
alternative path to the fine-grained (i.e. exact) madvise by flagging
just the first two pages as needed (see TWO_PAGES). Implement
alternative path that records the last madvise()ed area to avoid
redundant calls to madvise() on identical areas (due to
page-alignment constraints) -- see CHECK_MADVISE_OVERLAPS. Implement
path for USE_DIRECT_IO.
- configure: add check for O_DIRECT flag to open(2). Add option
--enable-direct-io. Add _GNU_SOURCE to CFLAGS to silence warnings
about chroot which is marked LEGACY since SUSv2 and is a non POSIX
extension. Make checks for posix_fadvise() dependant on
--disable-mmap, since we do not need fadvise for the mmap case.

- add some more rrd_sterror calls to failure paths.
- make rrdtool updatev work like 1.2.23 (i.e. multiple values are still
broken, but at least updating a single value works; see
http://oss.oetiker.ch/rrdtool-trac/ticket/8)
- indent touched files.

Updates from Bernhard Fischer rep dot nop gmail com
- fix typo in rrd_fetch where rrd_read result was checked against an
incorrect size.
- in rrd_fetch, drop rrd_head_size in favour of rrd_file->header_len
- in rrd_fetch, make the message "post fetch" unambiguous (now past vs.
post).
- change usage of param rdwr of rrd_open: allow for RRD_READONLY,
RRD_READWRITE, RRD_CREAT, RRD_READAHEAD; adjust callers accordingly:
+ rrd_resize needs CREAT
+ rrd_dump may want READAHEAD
- implement FD based I/O in rrd_open, rrd_read, rrd_write, rrd_seek.
- in rrd_update, unify write_RRA_row().
- sort | uniq the -T in .indent.pro (info_t was duplicated)
- add stub of an option to use O_DIRECT to the configury
- in Makefile.am, simplify the "indent" invocation of find:
My find may not support "-o" resp. "-or" nor braces.
Using -name "*.[ch]" works everywhere, AFAIK.
