Aug 15, 2017 at 18:59 comment added Matthew Drury Of course you can. I suppose that I have this general opinion, and it is an opinion, that notation should only be used when it is clarifying. It's the kind of thing to me that is best used in moderation. I tend to use more text and words than other math/stats communicators, because that's more clear to me.
Aug 15, 2017 at 15:53 comment added Alex @MatthewDrury why not specify the dimensions? $x\sim N(0,1)$ where $x \in R^{50}$. This seems to be clear in specifying how long a vector is. This way you can have $x_i \sim N(0,1)$ where $i=1,\dots,3$ and $x_1 \in R^{10}$, $x_2 \in R^{100}$, and $x_3 \in R^{1000}$. This makes it clear that three samples a being drawn, each having a different number of draws.
Aug 15, 2017 at 6:22 comment added Matthew Drury I thought of something similar, but it bothered me a little that the i.d. part is extraneous.
Aug 15, 2017 at 6:16 comment added Glen_b This is good -- however, notation can communicate independence, for example $X_i \stackrel{\text{iid}}{\sim} N(0, 1),\, i=1,2,...,50$
