What programs, applications, would you recommend to work on your computer and why? I am not talking about the name of a specific company (brand) to avoid being accused of surreptitious advertising, but about the specification of an IT tool that, in your opinion, enables good data analysis and a tool that you perceive as future-oriented for the work of an economist a macro and micro data analyst. What tool with what device (computer) makes a good analytical set? I believe that investments in IT applications, regardless of what our university has installed on computers, are an important part of our individual choices and work with data. I also think that the tools we choose ourselves and learn to use them well at work, affect the final results of our analytical projects. What's your opinion?
