| Mar 21 at 17:21 | comment | added | Iosif Pinelis | I think its OK to write a blackboard-bold P and a blackboard-bold R when writing on a blackboard -- but not OK when TeX can be used, with all its different fonts. | |
| Mar 21 at 17:18 | comment | added | Iosif Pinelis | @tsnao : I think this is a matter, not of a clash of notations, but of esthetics and of esthetical awareness. Isn't is just nicer when objects of the same kind are denoted similarly while objects of different kinds are denoted differently? | |
| Mar 21 at 16:58 | comment | added | tsnao | @IosifPinelis, it's a matter of taste. Who am I to argue, but clash of notation is not a convincing argument for me since 1) it happens all over math and 2) there's absolutely zero chances of confusing the probability with complex numbers | |
| Mar 21 at 16:31 | comment | added | Iosif Pinelis | @tsnao : Of course, this notation is common. Still, it should not be used. | |
| Mar 21 at 12:54 | comment | added | tsnao | @Grigori, you will probably find what you're looking for if you Google total variation distance and its bounds. Moreover, there's some notation abuse going on in your suggested bound: the left-hand side doesn't depend on $\mathbf{z}$ or $\mathbf{v}$, but rather on their laws. | |
| Mar 21 at 12:52 | comment | added | tsnao | @IosifPinelis, I think it's pretty common to use blackboard bold in this context... In fact, most of the books I've seen write it like this. | |

| Mar 21 at 12:40 | comment | added | Iosif Pinelis | Do not use $\Bbb P$ to denote the probability. Use $P$ or $\mathsf P$ or $\text{P}$ instead. The blackboard-bold font is reserved to denote sets such as $\Bbb R$, $\Bbb C$, etc. | |
