CIOs are readying for another demanding year, anticipating that artificial intelligence, economic uncertainty, business demands, and expectations for ever-increasing levels of speed will all be in play for 2024. But at the end of the day, it boils down to statistics. Statistics can be very misleading.

And to do so, a solid data management strategy is key. More importantly, we also have statistical models that draw error bars that delineate the limits of our analysis. Good data scientists can also reduce some of this uncertainty through cleansing. Good developers can catch some of these issues through validation.

If $Y$ at that point is (statistically and practically) significantly better than our current operating point, and that point is deemed acceptable, we update the system parameters to this better value. Crucially, it takes into account the uncertainty inherent in our experiments. And sometimes even if it is not[1].)

We often use statistical models to summarize the variation in our data, and random effects models are well suited for this — they are a form of ANOVA after all. In the context of prediction problems, another benefit is that the models produce an estimate of the uncertainty in their predictions: the predictive posterior distribution.
