## How to Navigate the STATISTICA Workspace

by STATISTICA How-To on Tuesday, October 29, 2013 7:30 AM

Analysis projects can be carried out in a variety of ways with STATISTICA. For Enterprise and Data Miner users, one option is the Workspace, which provides a visual way of performing your analysis tasks that additionally makes the process repeatable. The Workspace shows a symbolic representation of the flow from the input data through any data preparation and cleaning steps to exploratory and analysis tools. The flow continues to the output reports...

## How to Customize Axis Labels to Show Logical Date Intervals

by STATISTICA How-To on Wednesday, October 02, 2013 12:17 PM

Visualizing data by date is a great way to explore trend. However, because time intervals are not fixed (e.g., a month can be from 28 to 31 days), a fixed axis scaling may not give the most logical axis representation of dates. Suppose you have data that is collected daily but you want to label the axis in weekly, monthly, quarterly, or yearly intervals. With a new feature in STATISTICA 12, you can easily control the label of the axes in a way that is relevant and makes sense for time...

## How to Understand Text Labels

by STATISTICA How-To on Friday, August 30, 2013 3:26 AM

In STATISTICA, text data can be stored either as text or with text labels. When text data is entered in a spreadsheet, each unique text string can be assigned a numeric code. So the data are stored both as a number, which is hidden, and the text we see. In this article, we will discuss what text labels are and some of the benefits and common questions associated with text data and the use of text labels...

## How to Estimate a Regression Model Subject to Parameter Constraints

by STATISTICA How-To on Friday, July 26, 2013 12:31 PM

What if it is desired or necessary to compute a regression model, while ensuring that one or more parameters conform to a set of constraints? This article will explore one avenue of constraining model parameters during the regression function computation using the custom loss function.

## How to Most Efficiently Store Your Data

by STATISTICA How-To on Monday, June 24, 2013 4:48 AM
When working with large data files, it becomes important to look for ways to make one's processes more efficient. File size and computation times can both be affected by how data is stored. Many variables can be stored more efficiently merely by changing a few settings. In this article, we will explore the various methods to help make spreadsheet storage and computations more efficient...

## How to Compare Yearly Patterns Graphically

by STATISTICA How-To on Friday, May 24, 2013 1:34 AM

Plotting data across time helps to reveal interesting patterns and relationships. This was true of a study of weather and temperature patterns in Illinois that was conducted by Carl von Ende from the Department of Biological Sciences at Northern Illinois University. The goal was to visually compare the trends in temperature between two years, 2008 and 2009. In this article, we will explore the steps needed to create such a plot, including the creation of new variables, using time and date functions and graph customization tools...

## How to Use Breakdown Analysis for Non-Factorial Tables

by STATISTICA How-To on Wednesday, March 06, 2013 10:51 AM

STATISTICA can calculate descriptive statistics for dependent variables in each of a number of groups defined by one or more grouping, or independent, variables. A breakdown analysis is normally used as an exploratory data analysis technique. The typical question that this technique can help answer is very simple: are the groups created by the independent variables different regarding the dependent variable?

## How to Customize Boundaries in a Histogram

by STATISTICA How-To on Monday, January 28, 2013 10:47 AM

One challenge facing data analysts is creating data visualizations that convey the most information in the simplest manner possible. Histograms are used to visualize frequencies within continuous data to show how the data is distributed. In this article, we will look at how to customize histogram bins using the boundary method, which is the most flexible option for creating bins for a histogram. With this method, there is no need for equally spaced groupings, giving you more control over the display...

## Using Case States to Color or Mark by Category in a Graph

by STATISTICA How-To on Thursday, December 27, 2012 1:35 PM

One of the areas in which STATISTICA took first place in the 2011 Rexer Data Mining Survey is an often-overlooked but very important area in data analysis: strong graphical visualization of models. Large amounts of data or very complex ideas can be conveyed using a single still image. STATISTICA’s graphical tool set makes it easy to generate such images, and the ability to customize these images is limited practically only by the bounds of your imagination...Let's start with the Rats.sta sample data set in STATISTICA...

## Saving Graphics with Custom Settings for Dots Per Inch

by STATISTICA How-To on Thursday, November 29, 2012 5:43 PM

As you most likely already know, the graphics capabilities in STATISTICA are astounding. The ability of this software to visually display data is practically limited only by the imagination of the user, with enough ability for customization to suit most any need. There are times that customization of the printing of graphics is needed as well, such as customizing settings for dots per inch (DPI). STATISTICA has been designed so that you can save graphics with custom DPI settings...
