Combined text and graphics reports can be created in the report window by creating a new report (using the Create New Document - Report tab, accessed from the File - New menu) and clicking the Add to Report toolbar button to add individual spreadsheets and graphs. You can also select the Also send to Report Window check box and the Single Report (common for all Analyses/graphs) option button on the Output Manager tab of the Options dialog (accessible via the Tools - Options menu) to create an automatic report of all output created during your analyses.
To print the report, select Print from the File menu (or press CTRL+P) to display the Print dialog. Use the options in the Print Range group to specify what pages to print. To print the entire report, select the All option button. To print a range of pages, select the Pages option button and specify the range using the From and To boxes. To print the selected portion of the report, select the Selection option button.
RTF (Rich Text Format) is a Microsoft standard method of encoding formatted text and graphics for easy transfer between applications. When reports are saved in Rich Text Format (*.rtf), all file formatting is preserved so that it can be read and interpreted by other RTF-compatible applications (e.g., Microsoft Word).
The STATISTICA Report format (.str) adheres to RTF conventions; however, saving reports in the default STATISTICA Report format (*.str) ensures that reports will be opened in STATISTICA, giving you complete access to the report tree. In order to open the report in an RTF-compatible application, select Save As from the File menu to save the report as an RTF file. You can then open it in any RTF-compatible application.
Yes. You can use STATISTICA Reports to combine text and graphics by creating a new report (using the Create New Document - Report tab, accessed from the File - New menu) and clicking the Add to Report toolbar button to add individual spreadsheets and graphs to that report. Note that this is only one way you can create reports of your analyses in STATISTICA.
Use the Print Preview dialog, accessible by selecting Print Preview from the File menu when the report is active or clicking the Print Preview button.
You can position the desired text on the printed page by adjusting the margins (specify the Left, Right, Top, and Bottom margin widths, or drag the margin lines with the mouse pointer, as shown above). You can also create a header and footer for the document.
To create an analysis report, select the Also send to Report Window check box and the Multiple Reports (one for each Analysis/graph) option button on the Output Manager dialog (accessible from the File - Options menu). When used together, these two options automatically generate a report of all spreadsheets and graphs associated with a single analysis.
To automatically send all results to the same report, select the Also send to Report Window check box on the Output Manager tab of the Options dialog (accessible by selecting Output Manager from the File menu). Then select the Single Report (common for all Analyses/graphs) option button. When used together, these two options automatically generate a report that contains all of the results and graphs created in STATISTICA (from the time the options are specified).
Yes. Select Save As from the File menu to display the Save As dialog. To save the file using an *.htm extension, select HTML Files from the Save as type group.
Note that any graphs in the report are saved as *.png files in the same folder as the HTM file using the following naming convention: reportname_pict0001.png, reportname_pict0002.png, etc. You can save graphs as JPG files, instead. To do this, select Options from the Tools menu to display the Options dialog. Select the Reports tab, and then select the JPEG format option button in the Export HTML images as group.
The most direct way to create a new report is to select New from the File menu or click the New Report toolbar button. In the Create New Document dialog, select the Report tab and specify whether you want to create the report as part of a new workbook or a stand-alone report. Alternatively, STATISTICA will create a new report for you (and add the active document to it) when you select New Report from the File - Report menu or the Add to Report toolbar button.
Yes. You can create a customized header or footer for a STATISTICA Report (or any other document) that can include information such as the date, time, or the name and logo of your company. To create a header or footer, select Header/Footer from the View menu. This displays the Modify Header/Footer dialog in which you can select a default header or footer or create a custom header or footer.
Yes. When you add items to a report, they are inserted with generic document names (i.e., spreadsheet). However, you can rename report items (using a variety of Windows standard renaming conventions) so that they are more descriptive. For example, you can click to select an item in the report tree and press F2. Then enter the new name for the item and press ENTER.
Yes. The STATISTICA Report supports an entire range of drag-and-drop features within the report tree. By right-clicking on an item in the report tree, you can drag that item to a new location within the tree.
Yes. In addition to using drag-and-drop features to rearrange report items, you can use cut (CTRL+X), copy (CTRL+C), and paste (CTRL+V) functions. For example, if you have a report that contains two spreadsheets and a graph, you can rearrange the order of the spreadsheets by using cut and paste functions. To move (cut) a spreadsheet (or other document) in a report, right-click on the spreadsheet and select Cut from the shortcut menu (or press CTRL+X). This action places a copy of the item on the Clipboard while removing it from its current location in the report.
To paste the spreadsheet into a new position in the report, right-click in the report where you want to place the spreadsheet, and select Paste from the shortcut menu. Alternatively, you can press CTRL+V. This action places the spreadsheet (that you had cut to the Clipboard) in the desired location in the report. Note that the pasted object is placed above the object that you right-click.
STATISTICA provides a variety of supplementary information that can be included with graphs or spreadsheets from specific analyses when they are sent to a report. You can specify on the Output Manager tab of the Options dialog (select Options from the Tools menu) how much information to include.
Displaying supplementary information. Select the Display supplementary information check box on the Output Manager tab of the Options dialog and then drag the slider to the right to select the amount of supplementary information to be included in the report. Note that the Display supplementary information check box is only available if the Also send to Report Window check box is selected.
These two analyses both produce Breakdown tables. If the data is well balanced, there is no difference between the two. However, when the combination of your categories is sparse, the new Breakdown analysis will produce a much denser table by eliminating the empty cells.
In the Breakdown & One Way ANOVA analysis, an alternative way to display the Breakdown Table of Descriptive Statistics table is available. You can organize the table with main group (rows) and sub-group (columns) variables in Breakdown (By Group) Statistics (the results will be the same, but the layout of the table will be different).
A Gage Linearity and Bias Study answers the questions "How biased is my gage when compared to a master value?", and "Does the accuracy of my gage change when the size of the parts being measured changes?". These are called Bias and Linearity, respectively.
This means that your gage is not accurate when measuring parts. If a gage is unbiased, this does not mean that every measurement is correct. Rather, an unbiased gage means that multiple measured values, on average, will be equal to the true value for the part being measured. Although the gage is accurate (unbiased) on average, a Gage R&R study is needed to determine how much variation (precision) you can expect in repeated measurements of the same part.
This means that the accuracy of your gage changes depending on the size of the parts being measured. For example, the gage may not have any bias for parts in the middle of the gage's operating range, but may have significant bias (on the plus or minus side) when parts having sizes at the high end of the gage's operating range are measured.
These tell you what percent of your overall process variation are due to gage linearity and gage bias, respectively. Large values for these percentages indicate that this gage may not be sufficient for measuring parts from this process.
Look for a fitted regression line that is not horizontal. A line with a slope that is not close to zero indicates that the gage has a linearity problem across the operating range used for this study. Also, look for outliers in the plot of individual measurements. Outliers could indicate errors in data collection and recording, or problems measuring certain specific parts.
Refer to the Regression output to see if there is enough evidence in this study to conclude that the slope is truly not zero (not horizontal). A p-value smaller than .10 or .05 indicates strong evidence that the gage has a linearity problem. Also, look at the %Linearity values to see how much of the variation in the overall process is coming from this linearity problem.
Yes. STATISTICA Link Analysis is capable of multi-tasking, enabling you to perform simultaneous Association and Sequence analyses, with minimum effort on your part. All you have to do is to identify the Sequence and Association variables and STATISTICA will do the rest.
STATISTICA Link Analysis uses a novel and state-of-the-art algorithm based on a tree-building technique for extracting Association and Sequence rules from data.
Yes. STATISTICA Link Analysis provides convenient and effective ways of saving your existing models for later deployment and use. The first method employs an efficient relational database technology to store Association and Sequence models. The second method uses the Predictive Model Markup Language, which is particularly fast to execute.
Yes. Saved models can be loaded into STATISTICA SAL for re-training and updating using either the original data (used to create the model) or data sets containing new transactions. This feature enables you to update your models without starting your experiments from scratch, thus saving you time and effort to update your models for predicting future data in a rapidly changing market.
Given the ability to perform Multidimensional Association and Sequence Mining and the capacity to extract only rules for specific items, the program is well suited for Predictive Data Mining.
STATISTICA SAL can be applied to any data set that contains market-basket type data. The market-basket problem assumes that there are a large number of products that can be purchased by the customer. Such products can be, for example, supermarket items or different insurance plans, etc. Customers fill their basket with only a fraction of the available items. STATISTICA SAL can use this information to predict what customers will purchase and, hence, help you to boost your sales and meet the supply and demand in your business.
