quantile standard error r Allegan, Michigan

The formula that you give --- which is exactly the same as that which appears in Cramer, page 369, would appear to imply that the variance is infinite when f(Q.p) = I have read at least 20 empirical papers where this is applied either in the time-series or the cross-sectional dimension and haven't seen a mention of standard error choice. The default value is “sqroot”, which uses the square root of the sample size. Only the first elements of the logical arguments are used.

I got values for tau but I did not manage to evaluate errors or variances of these values. Is there anything that one can do in instances where f(Q.p) = 0? For different distributions this can be reversed as Jim pointed out. I know thatx<-rlnorm(100000, log(200), log(2))quantile(x, c(.10,.5,.99))computes quantiles but I would like to know if there is any function tofind standard error (or any dispersion measure) of these estimatedvalues.And here is a
