Improvements in PS QUAESTIO PRO 6 include a new way of presenting survey questions, a new look of responses with a scale rating, and on the analytical side - numerous improvements to the IBM SPSS Statistics engine and PS IMAGO PRO 6.
New custom question types
- SLIDER GRID - a new way of presenting tabular questions
A classic single response grid question whose presentation has been modified to form a single element in a row. Each time you mark the answer on the scale, you will proceed to assess the next subject, with the option of returning to the elements already selected.
- STAR RATING answers
A classic single response question where each of the answers are presented in the form of an asterisk symbol.
New version of analytical engine IBM SPSS Statistics 26
New options in the Analysis menu
- Quantile regression – models the relationship between a collection of predictors (independent variables) and specific percentiles (or quantiles) of a predictive (dependent) variable, most frequently the median;
- ROC curve analysis – a useful tool for assessing the accuracy of model prediction by plotting the sensitivity to a (1-specificity) classification test (at a threshold changing over the whole range of diagnostic test results).
Updated procedures and command language
- improvements to the procedures using Bayesian statistics:
- one-way ANOVA test with repeated measurements;
- one sample Binomial distribution;
- one sample Poisson distribution;
- Fleiss’ kappa added to Reliability analysis procedure for verification of conformity of assessments of several assessing persons;
- improvements to the functionality of syntax procedures:
- MATRIX procedure;
- Generalized linear models (GENLINMIXED);
- Mixed linear models (MIXED);
- changes to the Production tasks procedure related to reporting and planning of batch tasks, including the possibility to:
- INSERT HIDDEN feature in the Command Editor to send jobs to the IBM SPSS Statistics Server;
- replace IBM SPSS Collaboration and Deployment Services with Microsoft Windows Task Scheduler or MacOS Automator for performing scheduled tasks.
Docker containerization technology
Docker is a tool with which you can place the program and the libraries it requires into a portable, virtual container. This lightweight option can be run on almost any Linux server.
The Docker solution is a lightweight, open source project offering an additional protective layer for the application.
New in the Predictive Solutions menu
- Join files procedure:
Combine multiple SAV files (by adding observations) located in the specified folder, with the option of adding to the file a variable identifying the data set.
The procedure also allows to select a template file with descriptions of variables, to which additional observations will be added.
- Create calendar procedure:
Create a new dataset on the basis of the specified start and end date, in which an observation is created for each day in the given range. Add additional variables with information about the year, quarter, month, weekday or day of month.
