5.8
Users find online resources valuable for IBM SPSS support, though direct support is generally prompt, courteous, and solution-focused.
Sentiment score
7.0
Weka's customer service is praised for responsiveness and community support, but some report slow responses and insufficient technical help.
The customer support from Weka is probably the best of any company I have ever worked with.
Staff Infrastructure Engineer at a manufacturing company with 201-500 employees
Technical support for Weka is very good, and I rate it a 10.
Phd at a educational organization with 51-200 employees
they were very good and available twenty-four hours a day, seven days a week
Student at Rochester Institute of Technology
 

Scalability Issues

Sentiment score
5.9
IBM SPSS Statistics is praised for scalability but may face challenges with extremely large datasets or older hardware.
Sentiment score
6.2
Weka's scalability varies; effective with resources but struggles with high user numbers and requires frequent fine-tuning.
Scalability for Weka refers to the ability to expand, the ability to increase the number of users, and the ability to increase the amount of data, among other factors.
Phd at a educational organization with 51-200 employees
Weka struggles with large data sets imported into it.
Student at Rochester Institute of Technology
Weka is amazing in terms of scalability because we can scale at any time as long as we have the machinery.
Staff Infrastructure Engineer at a manufacturing company with 201-500 employees
 

Stability Issues

Sentiment score
7.4
IBM SPSS Statistics is reliably stable, efficiently handling large datasets, but newer versions may face stability issues under heavy data loads.
Sentiment score
7.8
Weka is stable but requires accurate predictor selection and resources; improvements in performance, visualization, and documentation are needed.
 

Room For Improvement

IBM SPSS needs better visualization, big data support, modern interface, automation, and affordable licensing for improved usability and analysis.
Weka needs better package management, Python integration, improved scalability, and user-friendly features for enhanced performance and usability.
It does not handle merging effectively and automatically cancels the data set, even if it was running for a whole day, ultimately indicating it cannot handle the data set merging.
Data Analyst at Toluna
I believe that the owners of IBM SPSS Statistics should think about improving the package itself to be able to treat unstructured data.
Associate Professor Of Statistics at a university with 10,001+ employees
I'm unsure if SPSS has a commercial offering for big servers, unlike KNIME, which does.
Emeritus Professor of Health Services Research at University of South Wales
Needed improvements for Weka would be the documentation and the ability to have zero downtime when upgrading the software.
Staff Infrastructure Engineer at a manufacturing company with 201-500 employees
I think Weka needs to improve in integrating Python into Weka, which would help users much more.
Student at Rochester Institute of Technology
 

Setup Cost

IBM SPSS Statistics' high pricing limits adoption, especially for advanced features, despite discounts for universities and students.
Weka is cost-effective and accessible, offering both free and paid versions to suit different organizational needs.
My experience with pricing, setup cost, and licensing for Weka is that I think it's a fair price since we are using it academically, so it is completely free to download and use.
Student at Rochester Institute of Technology
Pricing exactly what we would expect for this type of software in our environment.
Staff Infrastructure Engineer at a manufacturing company with 201-500 employees
 

Valuable Features

IBM SPSS Statistics offers user-friendly, robust analysis tools, supports large datasets, integrates Python, and provides extensive statistical modeling options.
Weka's simplicity, powerful visualization, ease of use, and diverse algorithms make it ideal for data analysis and education.
Predictive analytics is the most important part of analytics.
Associate Professor Of Statistics at a university with 10,001+ employees
IBM SPSS Statistics is secure, and the fact that only licensed users can access it is beneficial.
Data Analyst at Toluna
I mainly used it for cross tabs, correlation, regression, chi-squared tests, and similar analyses often seen in published papers.
Emeritus Professor of Health Services Research at University of South Wales
Weka processes a large set of data sets without needing to write any type of code.
Student at Rochester Institute of Technology
Weka is incredibly easy to use because there is a web UI that allows us to create and resize file systems at will, making different directory structures available to different users at any given time, and the speed is exceptional.
Staff Infrastructure Engineer at a manufacturing company with 201-500 employees
Weka is very easy to use, is very complete, and provides many benefits to the end user.
Phd at a educational organization with 51-200 employees

Associate Professor Of Statistics at a university with 10,001+ employees
Advanced predictive analytics have supported my research and student projects across many methods
The only function I may need to be added or hope to be added to IBM SPSS Statistics is how to treat unstructured data. This mainly exists with IBM SPSS Modeler, but I do not think it is able to treat something like videos and similar content unless you are using languages like Python inside IBM SPSS Modeler or inside IBM SPSS Statistics. For the menu itself, for the selection, it does not exist. Thinking of the future, I believe that the owners of IBM SPSS Statistics should think about improving the package itself to be able to treat unstructured data.

High-speed shared storage has accelerated AI research workflows and supports massive job queues
The best features Weka offers are high speed, exceptional performance, and reliability. It is probably the best file system I have ever used. These features have helped my workflows and users by enabling us to train and perform inferencing of AI workflows of proteins against target diseases, which allows us to run jobs in approximately half the time that we would with slower storage. Weka is always available, incredibly reliable, and backed up, so we could not do this work without it. Additionally, Weka is incredibly easy to use because there is a web UI that allows us to create and resize file systems at will, making different directory structures available to different users at any given time, and the speed is exceptional. Weka has positively impacted my organization because we previously had NFS, which would take down the cluster when under high load. Now we have no concerns about highly loaded multiple thousands of jobs running simultaneously against this file system. The system handles it without any issues. To share more about the scale, we have anywhere between 1,000 to 10,000 jobs in the queue at any given time, and the system handles it without any problems. Our volumes are approximately half a petabyte on one system and about a third of a petabyte on another system for various storage uses, and it enables all our work to go efficiently.
