        <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.

	<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.

	<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

<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>
