Statistical packages are software titles, such as JMP and GNU Octave, and programming languages, such as MATLAB, R and SAS, that are used to discover, explore and analyze data and suggest useful conclusions, either to learn something unexpected or to confirm a hypothesis. The field includes the design and analysis of techniques to give approximate but accurate solutions to hard problems in statistics, econometrics, time-series, optimization and 2D- and 3D-visualization. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.
I have a set of data (attached) which shows the volume of web traffic by Country, trended weekly. I'm trying to learn/find a statistical method that help me analyze the data in the following way:

What am i missing ?
Hi guys ;
I'd made a program to calculate matrix by using Gauss-Jordan Method.
But when I ran the program it ended with Overflow error.
Need your helps guys
Thanks
Hi, could anyone provide me with a Gauss elimination method in Delphi code? All I need is the basic body of the algorithm, without pivotization and substitution. If you could add some commentory to th…

Hi all,
We need to be able to read/write JMP file format using .NET (C#; C++, managed or not, could also be a solution). The JMP file is being used by SAS for import/export of data sets, and is of mi…
