comment Why don't we use significant digits?
@gung What I was meaning to ask was that what is the precision of the end points of a CI? How many digits are valid, say, when you're calculating a Wilson CI for a binomial proportion?

@gung How do you decide to represent the endpoints of the CI with two decimals?

comment Weak convergence of a double sequence of random variables
@SebastianZ, thank you for the elegant solution. I was stuck at the first equality, since $Y_n - Y_m$ doesn't converge to zero, but your second equality nails it and fixes the problem.

@Did I agree, if $X$ and $Y$ aren't independent (say $X$ = $Y$), then funny stuff happens. Thanks for pointing it out.

Come to think of it, I agree with Glen_b. This would be a good place to point out the incorrect terminology.

To avoid confusion, I removed the incorrect term from your title.

Yes, cumulative density function is meaningless. I believe the article you linked to is trying to talk about cumulative distribution function and by mistake calls it cumulative density function.

I have never heard the expression "cumulative density". Can you show an example where it is used?
