Statistics is an evolving field. The past 20 years have shown how this discipline changed. While new statistical models have appeared, computers became faster and cheaper, allowing professionals to apply these new methods with little trouble. Moreover, more data are generated, collected, and made accessible. Therefore, everyone with Internet access can download new data and analyze it independently. While traditional concepts such as inference, aggregation, likelihood, and experimental design are still valid, there are real-world problems that cannot be addressed in the same fashion as before.
