What's new in IBM SPSS Statistics 27.0.1.0

Dec 13, 2020
  • Today we are proud to announce the general availability of SPSS Statistics 27.0.1.0. This modification release introduces new statistical tests, enhancements to existing procedures and functional enhancements that will improve everyday usability. Like a traditional Fix Pack, this modification release includes many quality improvements, but with the added benefit of those new additions.
  • Statistical Procedures and Enhancements:
  • Z-Tests and confidence intervals for Proportions and differences in Proportions: For One-Sample, Paired-Samples, Independent-Samples analyses.
  • Found under the Analyze > Compare Means menu, the new Proportions procedure allows users to test for differences in population proportions and construct confidence intervals on observed differences using a variety of methods for each type of analysis.
  • Reliability Analysis Enhancement - McDonald's Omega:
  • As part of the Reliability procedure, McDonald's Omega allows users an alternative to the Cronbach’s Alpha statistic. To find this enhancement go to Analyze > Scale > Reliability Analysis, and under the Model dropdown on the Reliability Analysis dialog, select Omega.
  • Bivariate Correlation Enhancement - Added Confidence Intervals:
  • This enhancement in SPSS Statistics 27.0.1.0 is found in the dialog menu of Bivariate Correlations under the Confidence Intervals sub dialog. Users will be able to set the confidence interval parameter, apply the bias adjustment if desired for Pearson Correlation, and choose between various methods for other correlation coefficients.
  • Along with the new additions above we have also included confidence intervals for CONTRAST output in one-way ANOVA, added bootstrapping and multiple imputation to Proportions, and made an enhancement to multiple imputation predictive mean matching to enable the ability to choose the number of potential matching cases.
  • Usability Improvements:
  • Session Management - Restore Points:
  • This extension to the auto-recovery functionality introduced in SPSS Statistics 27.0.0.0 allows users to save a point in time in their analysis that users can revert back to if needed later in the analysis, while still enabling the user to continue down the current analytic path. Session Management is found on the Welcome Dialog on the Restore Points tab next to the Recent Files and Sample Files tabs. On the Restore Points tab users will find both their Auto-Recovery files, as well as saved Restore Points.
  • Output Enhancements - Editor Experience:
  • Several enhancements were introduced in SPSS Statistics 27.0.1.0 for Chart Builder, as well as the Table & Chart Editors. These improvements decrease the number of clicks needed to get customizable output in the application by utilizing new toolbar additions and experiences.
  • An improvement to SPSS Statistics Syntax was also introduced in SPSS Statistics 27.0.1.0 which allows users to select variables from the active data set using type ahead functionality. This will improve efficiency in writing scripts and make it easier for users to find the correct variables to reference from the active data set.
  • Quality Improvements: Along with new features and productivity enhancements there were also several quality improvements made to the application for 27.0.1.0. A list of those fixes can be found here.

New in IBM SPSS Statistics 26.0.0.0 (Apr 9, 2019)

  • Execute New Quantile Regression Analysis
  • Compare Two ROC Curves
  • Run Enhanced Bayesian Procedures for One-Way Repeated Measures ANOVA, One-Sample Binomial, and One-Sample Poisson
  • Utilize Fleiss Multiple Rater Kappa for Improved Survey Analysis
  • Run MIXED, GENLINMIXED, and MATRIX Scripting Enhancements
  • Replace IBM SPSS Collaboration and Deployment Services for Processing SPSS Statistics Jobs with New Production Facility Enhancements

New in IBM SPSS Statistics 25.0.0.0 (Apr 26, 2018)

  • Execute new Bayesian statistics functions including regression, ANOVA, and t-tests.
  • Bayesian statistics is becoming very popular, because it circumvents a lot of the misunderstandings brought by standard statistics. Instead of using a p-value to reject or fail to reject a null hypothesis, Bayesian places an uncertainty on parameters and captures all relevant information from observed data. Our approach to Bayesian statistics is unique because our Bayesian procedures are as easy to run as our standard statistical tests. In just a few clicks you can run Linear Regression, ANOVA, One-Sample, Pair-Sample, Independent-Sample T-tests, Binomial Proportion Inference, Poisson Distribution Analysis, Pairwise Pearson Correlation, and Loglinear models to test the independence of two categorical variables. Bayesian Statistics are found in the Advanced Statistics module for Stats 25 and to Subscribers of the Custom Tables & Advanced Statistics add-on.
  • Quickly create attractive, modern charts and edit them in Microsoft Office.
  • Building modern, attractive, and detailed charts has never been easier. Our chart builder has been updated with the ability to create publication quality charts in just a few clicks. Now you can specify chart colors, titles, and templates as you’re building the chart. And, our new default template ensures a great looking chart even without modifications. In addition, now if you wish, you can copy most charts as a Microsoft Graphic Object so you can edit titles, colors, styling, and even chart type right in Microsoft Word, PowerPoint, or Excel. Charting in SPSS has never been this easy. All these charting features are found in the Base editions.
  • Extend your advanced statistical analysis with updates to MIXED, GENLINMIXED, GLM, and UNIANOVA.
  • We’ve responded to customer feedback by adding the most requested enhancements to a few of our most popular advanced statistics functions. The Mixed Linear Models (MIXED & Generalized Linear Mixed Models (GENLINMIXED procedures now provide random effects solution results (EBLUPs and continuous time spatial covariance structures. Also, the General Linear Model (GLM and UNIANOVA procedures have been enhanced with new features including profile plots with error bars, bar/line charts, an option to include grand mean, and an option to force the chart to include 0 on Y axis. GLM and UNIANOVA also now include new tests for heteroskedasticity and model specification, robust standard errors, and modified versions of Levene’s test. Most of these functions are found in the Advanced Statistics module for Stats 25 and to Subscribers of the Custom Tables & Advanced Statistics add-on, although UNIANOVA is found in the Base editions.
  • Write, edit, and format syntax faster with Syntax Editor shortcuts.
  • Here are a set of features for those users that are primarily syntax writers. We’ve added a bunch of features (and associated keyboard shortcuts to make writing, formatting, and editing syntax easier. Now with a simple keyboard shortcut you can join lines, duplicate lines, delete lines, remove empty lines, move lines up or down, and trim leading or trailing spaces. In addition, we’re introducing a new column editing mode which allows you to edit multiple lines at once. A killer feature here is the ability to copy data from the data editor (or Microsoft Excel and paste “down” across multiple lines. It’s a great feature – once you try it, you will no longer be able to go back to the earlier syntax editor. These syntax features are found in the Base editions.
  • Plus more.
  • We have a new merge UI that simplifies merging options, a simplified toolbar with some convenient buttons added, the ability to open and save Stata v14 files, as well as the ability to copy and paste data from the data editor with variable names or labels.
