Line Plot or Scatterplot?

by STATISTICA How-To on Wednesday, October 29, 2014 12:31 PM
Statistica How-To logoA line plot is usually used for visualizing a sequence of many numeric values (e.g., stocks over days, temperature across regions, etc.) In contrast, a simple scatterplot is widely used to explore the relationship between two numeric values.
 
You can use Statistica to create both types of graphs, which sometimes look very similar. However, there is a big difference in how Statistica treats the x-axis variable (i.e., the variable used to produce the horizontal axis) when producing each of these two types of graphs. Knowing this difference can help you choose the right tool for your needs.
 
Statistica senior analyst, Wendy Xie, demonstrates the difference in this month's article...

How to Unstack/Stack Data in Statistica

by STATISTICA How-To on Wednesday, September 10, 2014 2:15 AM

Statistica offers options to perform “unstacking” or “stacking” of data files to make them more suitable for statistical analysis. The general operation or restructuring of data is similar to a cross-tabulation of values (given certain categorical variables).

These operations are especially useful when accessing data from databases where individual data values are identified by case and variable IDs, and where each unique combination of these IDs is contained in a new row of the data file.

In this how-to article, Krista Beasley, Dell Statistica's Technical Support Manager, walks you through some simple scenarios...

Dell Software Execs on Analytics, Data Mining, and Statistica future

by STATISTICA on Wednesday, August 06, 2014 1:40 PM
KDnuggets logoIn June, KDnuggets.com's Dr. Gregory Piatetsky published a summary of 2014 KDnuggets Annual Analytics/Data Mining Software Poll results. In his accompanying commentary, he observed, "Statistica's share has now declined for 2 years in a row (from 14% in 2012 to 9% in 2013 and 1.7% in 2014). With the recent acquisition by Dell, it seems likely that Statistica will continue to lose market and mind share."

Why the best experts can’t always explain what they’re doing

by STATISTICA on Tuesday, August 05, 2014 1:25 PM

presenterAn engineer once told me this joke: A spider asked the centipede, “You have so many legs; how do you coordinate them all to walk?” The centipede pondered this question for a while, then a while longer, and longer; and the centipede never walked again.

Many industries are buried in data to the point that it overwhelms the traditional approaches to process monitoring and root cause analysis performed by process experts. Yet, human process experts can often develop a “sixth sense” about even the most complex processes...but, like the centipede, they may not be able to provide any insights on how they accomplish this feat...

Rescuing Businesses from the DIY Big Data Vendor Trap

by philler on Tuesday, July 29, 2014 2:47 PM

DIY hand Recently, I received a product positioning template to be completed for our advanced analytics platform, STATISTICA. When I came to the section where I was to describe the "industry problem," I was stuck, because every industry has its own kinds of problems that can readily be solved with analytics.

And then it finally hit me: there is at least one common problem that every business must face in every industry...

Predicting Best Treatment for an Individual Using Weight of Evidence (WoE) and Automatic Binning of Continuous Variables, Leading to Decisioning

by STATISTICA on Wednesday, July 09, 2014 7:36 AM
Linda A. Winters-Miner, Ph.D.Guest-authored by Linda A. Winters-Miner, Ph.D., of Southern Nazarene University in Tulsa, this mini-tutorial comprises excerpts of two tutorials from a book to be released this summer titled Practical Predictive Analytics & Decisioning Systems for Medicine by Winters-Miner, Bolding, Goldstein, Hilbe, Hill, Nisbet, Walton, and Miner (2014).

The first part is the introductory text from a tutorial (F-2) that concerns weight loss, which was authored by Winters-Miner (2014). The second part is a tutorial (J-2) that concerns the medical condition Disseminated Intravascular Coagulation (DIC), which was authored by Khichi, Parsons, and Winters-Miner (2014).

It is hoped that, by combining some aspects of both tutorials here, this mini-tutorial will...
