Negative Quartile
Hello, I have a doubt, but it is more statistic than just about R: How
the people deal usually with negative percentile and quartile? In my
concrete case, I want to know the distribution of an error, so the
nearest it is to 0 the better (I think it would be optimun to have the
nearest values to 0 in the lower percentiles). The best result would
be making the percentile of the absolute value (without sign), but the
sing is also important, and I need to keep it.
This results in the big negative values to be in the lower
percentiles, which are usually understand...
