Add-On Statistics for Data Analysis
Statistics for Data Analysis Add-Ons
The strong experience gained in the field of analysis allows us today to propose Statistics for Data Analysis, a solution
powered by IBM SPSS, which will allow you to make the most of the tool's potential in all phases of the study process.
The Add-Ons can be installed and used directly from the Statistics menu or implemented in existing automatisms by copying/pasting
the syntax, allowing you to customize your studies.

Automatic ID
This procedure allows cases to be duplicated a number of times equal to the value of a numeric variable.
Duplicate cases
This procedure allows cases to be duplicated a number of times equal to the value of a numeric variable.
Split Strings
This procedure allows a string variable to be broken down into several parts by identifying a character within the string itself.
Add Days
This procedure allows you to add any number of days to a variable in date format.
Contingency tables
This procedure makes it possible to customise the contingency tables, whose data are automatically imported into a new dataset, ready for subsequent analysis.
Tables for multiple-choice sets
This procedure allows you to customise the tables for multiple-choice sets via a dialogue box.
RSVP Chart
It is a bar graph superimposed with a graphic element to display the bar-on-bar variation, horizontally.
Ladder Plot
This is a graph usually used to visualise the effect of a treatment on the same set of subjects, before and after treatment.
Replace Outliers
This procedure replaces missing values with the average of the values of the group to which they belong.
Keep Information
This procedure allows cases to be deduplicated by keeping those cases that contain more information.
String deduplication
With this procedure it is possible to concatenate a list of string variables while retaining, on a case-by-case basis, only the unique values of the string variables.
Text Extraction
Questa procedura permette di scomporre una variabile stringa in due parti. La scomposizione avviene mediante l’individuazione di un carattere all’interno della stringa stessa.
File Division
This procedure is useful for dividing the file into sub-files based on the values assumed by a user-defined variable
Add 60 days
Procedure for adding 60 days end of month to a variable in date format.
Split random files
Procedure for randomly extracting two distinct sets of cases from a single file.
Esclude Outliers
Procedure to obtain a data file containing only those cases that belong to the range (average (control variable) -/+ n_times the standard deviation).
Remove Duplicates
Procedure that generates a data file containing only those cases that are NOT duplicated. Cases are selected by selecting one or more control variables to identify duplicate cases.
Case Validation
Procedure that generates a data file containing only those cases that comply with a set of constraints. Cases are selected by selecting one or more control variables and their respective constraints.
In this procedure, constraints are placed on at least two variables.
Simple Sample Base
This procedure makes it possible to determine the sample size in order to obtain results that reflect the survey population with a certain degree of accuracy.
