Empirical Quantile CI's can use Method 1 or Method 2

Which Method is better to use for Empirical Quantile CI calculations?

Answer:

In version 4.6.0.0, Joinpoint allows the use of Method 1 or Method 2 for Empirical Quantile confidence interval calculations. Studies suggest using Method 2 when the number of observations is as small as 10 and Method 1 when the number of observations is greater than or equal to 20.
