> h3. corr
> the standard defines corner cases when it should return null - but the
> current result is NaN.
> If N * SUMX2 equals SUMX * SUMX , then the result is the null value.
> and
> If N * SUMY2 equals SUMY * SUMY , then the result is the null value.
> h3. covar_samp
> returns 0 instead 1
> `If N is 1 (one), then the result is the null value.`
> h3. check (x,y) vs (y,x) args in docs
> the standard uses (y,x) order; and some of the function names are also
> contain X and Y...so the order does matter..currently at least corr uses
> (x,y) order which is okay - because its symmetric; but it would be great to
> have the same order everywhere (check others)
