Nov 9, 2017 at 21:41 comment added HBeel @Raskolnikov After reading the papers some more I think you're right. Am I correct in thinking that formally if a random variable is sub-Gaussian it has zero mean and that the bandit papers are actually suggesting the reward is the sum of some random variable (which defines the mean) plus a sub-Gaussian? I just feel like the bandit papers are abusing the definition a bit by calling the shifted sub-Gaussian a sub-Gaussian. I come from more of a math/computer-science background so I'm not sure if this is common in statistics.
Nov 9, 2017 at 18:52 comment added Raskolnikov I suppose it's just a matter of translating the variable by adding or subtracting a constant $\mu$. The definitions you give initially only want to treat standardized variables for convenience. But I don't see the problem to consider variables that would have a non-zero mean.
