<sammendrag> If you need a program for statistics, and you're
wondering which options you have, this article is for you.</sammendrag>
<hoveddel>
<avsnitt>There are generally three different programs for statistics available at NTNU; <uthev>Mintab</uthev>, <uthev>S-Plus</uthev> and <uthev>SPSS</uthev>.
In addition there is an utility called <uthev>SciCraft</uthev> under
development at NTNU. You also have access to various
programming languages and statistics-libraries through NTNU.
More information about this is available under <uthev>Other tools for statistics</uthev>. </avsnitt>
<os2>Minitab</os2>
<avsnitt>MINITAB is an interactive program for statistics with a
user-friendly interface. MINITAB is used as a educational tool
at NTNU. </avsnitt>
<avsnitt>With MINITAB we can read data from different sources, edit
data and perform calculations. We can also do many different
statistical analyses and present the results through
graphics, among others. MINITAB includes a programming
language.
</avsnitt>
<avsnitt>We have an unlimited "site"-license for Minitab at NTNU, and
the program can therefore be installed on your home computer.
<ekstern uri="http://www.ntnu.no/itea.info/programvare/minitab.html" tittel="Programvaretilbud, Minitab"> Information about system requirements and
other general information.</ekstern>. A tutorial is available on the cd, but
you can also find <ekstern uri="http://www.bath.ac.uk/bucs/software/statistics/minitab.html" tittel="Minitab Introduction">an introduction here</ekstern>.</avsnitt>
<os2>S-Plus</os2>
<avsnitt>S-PLUS is a comprehensive program for statistics. It is much
more advanced than Minitab and SPSS - The amount of built-in
functions are much larger. In addition it is possible to use own
programs in S-plus or forexample C++. The program have plenty
of graphical possibilities. S-plus is used a lot within
statistical research.</avsnitt>
<avsnitt>S-Plus is available through a collaboration purchase, and can
be used by all students at NTNU and all employees at those
institutes that have paid to be part of the collaboration. It is possible for
institutes and individuals to purchase into the collaboration.
Members of the Collaboration purchase:</avsnitt>

<os2>SPSS</os2>
<avsnitt>SPSS is a comprehensive statistical data handling and
data analysis tool. SPSS Base and a long complement of add-on
modules are available through NTNU. For more information about
the program see <ekstern uri="http://www.spss.com/no/products/statfamilie/oversikt.htm">SPSS
program information (Norwegian)</ekstern>.</avsnitt>
<avsnitt>All SPSS products are freely available to all students at NTNU,
and to all employees at the following faculties:</avsnitt>
<ul>
<li>SVT faculty</li>
<li>DMF faculty</li>
<li>NT faculty</li>
</ul>
<avsnitt>At the rest of NTNU, the program needs to be licensed yearly by a
personal license to individuals.</avsnitt>
<avsnitt>The agreement includes:</avsnitt> <ul type="dott">

<os2>SciCraft</os2>
<avsnitt>SciCraft is a tool that makes it possible to integrate methods from
other calculation software. SciCraft currently supports
<uthev>R</uthev>, <uthev>Python</uthev> and
<uthev>Octave/Matlab</uthev>. SciCraft also has built-in functions. It
is Open Source, and is therefore available freely from the SciCraft
website:</avsnitt>

<os2>Other tools for statistics</os2>
<avsnitt>In addition to programs purely for statistical purposes,there are
also various programming libraries with good statistical subroutines.
<infoweb aid="335">NAG Fortran 77, Fortran 90 and the C
library</infoweb> can be used for statistical calculations.
These libraries can be used together with various program libraries,
and are available for installation on employee computers and in
student computer labs. They can't be installed on student's personal
computers.</avsnitt>
<avsnitt>Another tool that is useful for statistical calculatons is <infoweb aid="133">Matlab</infoweb>. It is available for employees and
students at NTNU, but the toolbox for statistics is only available for
employees connected to the NTNU network. For license information and a
short introduction, see <infoweb aid="133">this link</infoweb>.</avsnitt>
