STATISTICA

Free Source for Datasets

Fri, 12 Mar 2010 17:13:00 GMT

I recently came across Hans Rosling's 2007 TED talk on poverty and statistics. (Video is embedded below.) The talk is entertaining and thought provoking.

Dr Rosling founded a non-profit organization called GapMinder. Their goal is to be:

“fact tank that promotes a fact based world view"

Gapminder is a good source for free

STATISTICA 6, Windows Vista, Windows 7

Thu, 11 Mar 2010 18:52:00 GMT

STATISTICA 6 is a 9 year old application. We released it in 2001.

It is not compatible with Windows Vista or Windows 7. You will need to upgrade to STATISTICA 9.

StatSoft is offering an upgrade discount for past customers. And you may find the new features in STATISTICA 7, STATISTICA 8 and STATISTICA 9 to be useful for your tasks.

Components of Variance in STATISTICA

Fri, 26 Feb 2010 15:30:00 GMT

A random factor is a variable of interest for which we selected only a subset of the population levels to test, but which we still want our results to be applicable to all levels possible. For example, suppose that in a factory we sample products from 5 workers, even though we have 100 workers total. Since we want our results to be generalizable to all workers in the factory, not just the 5 we selected, we would treat this variable as a random factor. When a process involves random factors, a common analysis is to calculate the variability in the overall process that is due to these random factors. To quantify this number, we will compute Components of Variance.

Following is a guide on how to compute the Components of Variance in STATISTICA:

How to Use STATISTICA Projects

Fri, 19 Feb 2010 22:26:00 GMT

STATISTICA projects provide the means to save your work and return to it later. A project is a "snapshot" of STATISTICA at the time it was saved, i.e., the tool saves your input data, results (graphs, spreadsheets, etc.), analyses, and/or Data Miner workspaces that are currently open into a single project. Upon opening the project, all of these items will be restored exactly as they were when the project was saved. This tool is a time saver, as it allows you to continue the analysis instead of starting it over again.
