Personally I grew up using SPSS and have always found it excellent. It takes time to master, and its not cheap, but it's worth the effort. And most of my work has been on public services. There is also à freeware version called PSPP which has similar functionality but some limitations.
When it comes to studying the public budget, several statistical software options can be valuable. some of them are:
IBM SPSS Statistics: It is widely used proprietary statistical software that offers a range of features for data analysis.
JMP: It is a data analysis software that combines interactive visualization with powerful statistical capabilities.
When selecting statistical software, it's important to consider various factors such as your proficiency in using the software, specific analytical requirements, and budget constraints. These factors play a crucial role in choosing the most suitable statistical tool to effectively analyze public budget data and facilitate informed decision-making.
