The features that I have found most valuable are the Bayesian statistics and descriptive statistics.
IBM SPSS Statistics offers transparency and confidence with dataset views post-transformation, features easy-to-create custom tables and macros for broad audience reports, and excels in machine learning and statistical modeling. User-friendly and ideal for novices, SPSS supports basic analyses but struggles with large datasets and lacks efficient data visualization. Improvements are needed in documentation, advanced modeling, predictive features, and technical support to enhance analytical performance and meet modern data handling expectations.
