Hot Fix for STATISTICA Version 10.0 MR1

The STATISTICA Version 10.0 MR1 hot fix, posted July 20, 2011, addresses issues in two analytic modules. StatSoft recommends that users apply this hot fix and re-run critical analyses to verify results.

1. An issue related to computations in the Generalized Linear/Nonlinear Models (GLZ) module was detected after the release of STATISTICA Version 10.0 MR1. Specifically, this issue was encountered when specific numeric conditions occurred during parameter estimation, and when repeatedly computing summary Goodness-of-Fit (GOF) statistics for the entire model (requesting that option from the Results dialog after the model estimation computations have completed). In some cases, the program may crash or may report inaccurate AIC values due to incorrect degrees of freedom computations. Other fixes were included to address the display of the Iteration History spreadsheet and for computation of the BIC value using the multinomial distribution.
    
2. An issue was detected after the release of STATISTICA Version 10.0 MR1 relating to occasional crashes and erroneous results experienced during modeling using the Cox Proportional Hazard modeling tools available from the Advanced Modeling pull-down menu (option Cox Proportional Hazards), when using forward, backward, or stepwise predictor selection methods.

In some circumstances, the program can crash, and/or produce erroneous final results (that are inconsistent with the results obtained when the respective model is estimated without forward, backward, or stepwise predictor selection). StatSoft strongly recommends that all users relying on the stepwise, backward, or forward predictor selection techniques in the context of Cox Proportional Hazard models apply this hot fix and re-run critical analyses to verify results.

Downloads

Before applying this hot fix, you must be already updated to Version 10.0 MR1. If you are still on Version 10, you can get the Version 10.0 MR1 update.

• Network/Enterprise Server: From your STATISTICA program file server, please download and run either the 32-bit or 64-bit hot fix installer, depending on the version(s) of STATISTICA 10 you have installed. To run the installation, double-click on the STATISTICA 10.0 Hot Fix V10MR1HFS004 file you downloaded and follow the on-screen instructions to complete the installation.
   
• Network/Enterprise Workstations with locally installed program files: (Note: If you are not sure if your workstation has locally installed program files, open Help -> About STATISTICA, and select the Modules tab. If the Full Path line refers to a C:\ drive or other local drive rather than to a server computer, then you have locally installed program files.) Please apply the hot fix to each workstation using the above Server instructions. Note that the hot fix will need to be applied to any subsequent workstation installations as well. Workstations that do not have locally installed program files do not require the hot fix.
   
• Single User: Please download and run either the 32-bit or 64-bit installer, depending on the version of STATISTICA 10.0 MR1 you have installed.

• Extremely large data sets are now supported in Data Mining modules (e.g., Interactive Trees, Boosted Trees, Random Forests, Cluster Analysis) that require iterative processing of the entire data set.

Excel Import Improvements

• Microsoft Excel 2007 (*.xlsx) importing for non-U.S. locales has been improved.

Statistics Enhancements

• Basic Statistics contains a new Percent of Valid Observation option, which is the proportion of valid observations for a selected variable to the number of cases reported for that variable.
• Generalized Linear/Nonlinear Models (GLZ) now generates:
  • Odds ratios and their confidence intervals
  • Receiver Operating Characteristic (ROC) Curve
  • Tweedie distribution
• Quality Control Charts now accommodate one-sided control limits, including X, X-bar, MA, EWMA, Individuals with Moving Range, and CuSum, which can be deployed to STATISTICA Enterprise.
• Survival Analysis contains a new Confidence Level field on the Regression Results dialog. The value in the Conf. Level field is used for constructing confidence limits for the parameter estimates and the risk or hazard ratio.

Data Miner Workspace Enhancements

• Scrollable trees are now part of Data Miner Workspace output.
• When adding nodes to the Data Miner Workspace from the node browser, a sound will now be produced to alert the user.
• In the Data Miner Workspace, the logistic regression for deployment node now offers model building techniques including stepwise and best subset regression. Nodes for deployment allow for easy comparison of model performance within the workspace.

Graph Enhancements

• Scatterplot graph markers using "outline style" are now transparent to better display multiple points clustered together.
• Box Plots now have ToolTip text to display N and case names.
• Multiple Plots (e.g., multiple scatterplot with one X variable and two or more Y variables) automated by SVB scripts now include data for newly added spreadsheet columns after the initial plot is created (without needing to delete and re-create the plot).
• Categorized graphs (such as means plots, box plots, missing data/range plots, and ternary plots) now have an Overlaid Layout option, which overlays all subsets in one graph and identifies them with colors and patterns.

Spreadsheet Enhancements

• STATISTICA Spreadsheets now support a user-entered comment in the audit trail.
• The Subset data management feature now has easier access to Spreadsheet Case Selection Conditions.
• Two new STATISTICA Visual Basic (SVB) function calls have been added to the spreadsheet object model to optimize the size of text variables based on the existing text:
  • OptimalTextVariableWidths

STATISTICA Data Miner

The STATISTICA Data Miner approach provides an intuitive graphical interface to enable those with limited data mining experience to execute a "recipe-like" step-by-step analytic process. With these intuitive dialogs, you can perform various data mining tasks such as regression, and classification. Other recipes can be built quickly as custom solutions. Completed recipes can be saved and deployed as project files to score new data. 

• The STATISTICA Data Miner workspace may be resized independently of the size of the window. Additionally, the 4 node placement rectangles within the workspace may be sized independently. The workspace may be scrolled to view any parts not currently visible.

STATISTICA Enterprise

• XBar-R or XBar-S charts can be created from aggregated data. 
• A new chart type of "Six Graph" graph can be selected for SPC Analysis Configurations that have variable charts defined.  
• Options for starting "this week" either on Sunday or Monday  
• Administrators may restrict the set of filtering operations to those that are logical for the data being filtered. 
• A Deployment option allows you to directly upload PMML into Enterprise SVB Analysis Configurations so that the PMML can be executed against a Data Configuration  
• STATISTICA Enterprise Reporter can now generate reports directly as Word documents (*.doc). This requires that Microsoft Word be installed on the machine where the Report is run. 
• The Ad hoc Analysis Configuration is a special type of Analysis Configuration that just returns the data from the associated Data Configuration without running any analysis or SVB. Running an Ad hoc Analysis Configuration is equivalent to exploring the associated Data Configuration. This is useful for users that want to use STATISTICA Enterprise to import their data, and then perform ad hoc analyses.
