New macro !PROXBIN was added on Kirill's SPSS macros page to "Various proximities" collection. The macro computes a large number of distance or similarity measures for binary (dichotomous) data. All most important coefficients designed s...

"Impute missing data" collection.

New python code.

Please visit Kirill's page, if you are interested.

Updates on Kirill's Macros page:

1. Considerably enriched with options macro to compute Gower similarity (see "Various proximities").
2. New procedure for hierarchical cluster analysis with exotic linkage methods: Hausdorff distance and other (s...

New functions to compare partitions (clusterings, groupings, classifications) where added to Kirill's SPSS Macros Page. Find there various measures of similarity of groups, like external clustering criteria and agreement indeces.

"Clustering criterions" collection has been further enriched on SPSS Kirill's Macros page.

Collection "Various proximities" has been updated on Kirill's macros page. There appeared SPSS macro !PROXQNT which computes a diversity of similarity or dissimilarity (distance) measures for quantitative data, the majority of them being...

"Clustering criterions" collection was considerably updated on Kirill's SPSS macros page. Clustering criterions are used to compare results in cluster analysis and to decide on the best number of clusters in it.

Syntax revision: Convert first letter of each word to uppercase (v.2)

Also the Python-based solution for this problem was added: Capitalize each word in a string variable

This is a version of syntax Replace values higher than n by the mean of the other values, adapted to capabilities of modern SPSS versions (tested with IBM SPSS Statistics 24). Code is much simpler as we don't need anymore to store aggreg...

New python script has been added to the collection. This is a more general (more flexible and powerful) solution for the problem of string validation, considered in Test SSN example in Syntax section. The solution uses regular expression...

SPSS Programming and Data Management Book page was updated with link to ZIP with Programming and Data Management for IBM Statistics, revision for version IBM SPSS Statistics 24. The link is guided to developers.ibm.com site.

Code highlighting features were added to the site. Now the collection and code portions scattered throughout the site are colored with syntax, VB-scripts, Python or R syntax rules, depending on code snippet language. This helps with code...

Another way to pass parameters to Python. New Python script by Albert-Jan Roskam.

Steve Sizmur PhD, Chief Statistician at Picker Institute Europe suggested this code. Thank you, Steve! It illustrates how to read data for a set of variables (var1 to var4), get the variable information from SPSS and then process them — ...
