comment Correct terminology for describing relative confidence interval
Thanks; and based on the answer by @tharen and comment by G Jay Kerns, "relative margin of error" is the terminology we now use.

comment Pooled regression vs non-pooled regression
I don't understand how the first paragraph describes pooled data, can you explain a bit more? Perhaps the key is what you mean by ignoring the bank effects, does this mean you are actually taking the average across banks for each ratio?

comment R - ARIMA model with long seasonal periods - Error: “length of x and xreg does not match”
I don't see any fourier1() on the webpage. Is it actually fourier()? Where has fourier1() come from? You would be more likely to get a good answer if you provided a reproducable example including the packages you have loaded.

comment Unbiased estimator from two SRS less duplicates
To expand on my first comment - it's not clear whether the $y_i$ you have is just the set S and you have just $n_s$ of them, with the duplicates removed; or whether you have all $m+n$ values of $y_i$ including the duplicates.

comment Unbiased estimator from two SRS less duplicates
If you have all the $y_i$, surely you also know $n_s$? ie just by counting the $y$s.

comment Developing a prediction model for bus stops
I find quite confusing the link between "reach a certain point" and "avoid that stop" and "missed a stop or not". I don't think the problem is statistical jargon, could you maybe re-word the problem more precisely about what in the real world it is about?

comment Unbiased estimator from two SRS less duplicates
This is unbiased but probably isn't efficient if n and m are different because $y_i$ in the smaller subsample are given more weight than those in the bigger subsample.
