Regression.pm is a multivariate linear regression package.
That is, it estimates the c coefficients for a line-fit of the type
y= c(0)*x(0) + c(1)*x1 + c(2)*x2 + ... + c(k)*xk
given a data set of N observations, each with k independent x variables
and one y variable. Naturally, N must be greater than k---and preferably
considerably greater. Any reasonable undergraduate statistics book will
explain what a regression is. Most of the time, the user will provide a
constant ('1') as x(0) for each observation in order to allow the
regression package to fit an intercept.
FICL is an extremely lightweight, fast, portable implementation of FORTH
which can be bound to C functions or even embedded within C/assembler
programs. This is a port for the current version of FICL. Older versions
can typically be found in /usr/src/sys/boot/ficl on FreeBSD with the
bindings needed by the OS loader.
OAuth is an open protocol to allow secure API authorization in
a simple and standard method from desktop and web applications.
liboauth is a collection of POSIX-c functions implementing the OAuth
Core RFC 5849 standard. liboauth provides functions to escape and
encode parameters according to OAuth specification and offers
high-level functionality to sign requests or verify OAuth signatures
as well as perform HTTP requests.
The intention of the nglogc library is to provide an easy to use and powerful
logging API with mechanism which allows to cram source codes with log
statements at the start of implementation and decide at the level of building
or at runtime which statements should be processed.
Therefore the log statements could be controlled by various log levels and
define switches are available to completely remove the call of the functions at
pre-processor time. So it is possible to switch on the logging only if it is
necessary or only print selected messages without any changes in the source
code. Different publishers are provided also as different formats of outputs to
fulfil the requirements for software development.
libfirestring is a string handling library that provides
maximum length aware string handling functions to programs.
Several functions provide saner interfaces than the standard
libc functions. libfirestring also provides functions that
are in most libc's but not provided for by ANSI C, enabling
programmers to write ANSI C-compliant code while using such
safe functions (strcasecmp, strncasecmp, snprintf).
libfirestring also includes functions for dealing with
reading configuration files in an easy to program fashion.
This library uses long long, which is part of the C99 standard
(previously a GNU extension). Your compiler needs to support
this in order for FireString to work.
Z80-asm is a C-source code available package which contains a 2-pass
Z80 assembler and a sophisticated Z80 monitor. This monitor can be used
as debugger, disassembler, emulator and more for a Z80-CPU.
BUFR = Binary Universal Form for the Representation of meteorological data.
BUFR is approved by WMO (World Meteorological Organization) as the standard
universal exchange format for meteorological observations, gradually
replacing a lot of older alphanumeric data formats.
This module provides methods for decoding and encoding BUFR messages, and
for displaying information in BUFR B and D tables and in BUFR flag and code
tables.
Installing this module also installs some programs: bufrread.pl,
bufrresolve.pl, bufrencode.pl, bufr_reencode.pl and bufralter.pl. See
https://wiki.met.no/bufr.pm/start for examples of use. For the majority of
potential users of Geo::BUFR I would expect these programs to be all that
you will need Geo::BUFR for.
ExtUtils::XSBuilder is a set modules to parse C header files and create XS
glue code and documentation out of it. Ideally this allows to "write" an
interface to a C library without coding a line. Since no C-API is ideal,
some adjustments are necessary most of the time. So to use this module you
must still be familiar with C and XS programming, but it removes a lot of
stupid work and copy&paste from you. Also when the C API changes, most
of the time you only have to rerun XSBuilder to get your new Perl API.
Osmium is a C++ framework for working with OSM data files. Osmium
can read OSM data in XML or binary format (PBF) and can call different
handlers for each OSM object.
HTSlib is an implementation of a unified C library for accessing common file
formats, such as SAM, CRAM, VCF, and BCF, used for high-throughput sequencing
data. It is the core library used by samtools and bcftools.
