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.</p> <p>Following is a guide on how to compute the Components of Variance in STATISTICA:</p> <p><img alt="Components of Variance in STATISTICA" width="293" height="406" src="/Portals/0/blog/Step 1.jpg" /> </p><a href=http://www.statsoft.com/support/blog/entryid/119/components-of-variance-in-statistica/>More...</a> http://www.statsoft.com/support/blog/entryid/119/components-of-variance-in-statistica/ http://www.statsoft.com/support/blog/entryid/119/components-of-variance-in-statistica/#Comments http://www.statsoft.com/support/blog/entryid/119/components-of-variance-in-statistica/ Fri, 26 Feb 2010 15:30:00 GMT 0 http://statsoft.com/DesktopModules/Blog/Trackback.aspx?id=119 <p><br /> <em><img height="181" alt="" hspace="10" width="197" align="left" src="/Portals/0/blog/Computer.jpg" />STATISTICA </em>projects provide the means to save your work and return to it later. A project is a "snapshot" of <em>STATISTICA </em>at the time it was saved, i.e., the tool saves your input data, results (graphs, spreadsheets, etc.), analyses, and/or <em>Data Miner </em>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.<br />  </p> <p> </p> <p><br />  </p><a href=http://www.statsoft.com/support/blog/entryid/118/how-to-use-statistica-projects/>More...</a> http://www.statsoft.com/support/blog/entryid/118/how-to-use-statistica-projects/ http://www.statsoft.com/support/blog/entryid/118/how-to-use-statistica-projects/#Comments http://www.statsoft.com/support/blog/entryid/118/how-to-use-statistica-projects/ Fri, 19 Feb 2010 22:26:00 GMT 0 http://statsoft.com/DesktopModules/Blog/Trackback.aspx?id=118 <h2><em><br /> STATISTICA</em> Receives Top Ratings <br /> Rexer Analytics 3rd Annual Data Miner Survey</h2> <div> <div><img alt="Rexer Analytics" align="left" width="246" height="40" src="http://www.statsoft.com/Portals/0/blog/rexer_analytics.jpg" />In a survey of 710 data miners primarily from industry conducted by Rexer Analytics, <em>STATISTICA Data Miner </em>received top ratings.
