Quantile Standard Error Based On The Maritz-jarrett Method

Contents

There are several methods.[1] Mathematica,[2] Matlab,[3] R[4] and GNU Octave[5] programming languages include nine sample quantile methods.

Our results also show that for two-sided confidence intervals and hypothesis tests, and in large samples, the bootstrap variance estimate is inferior to the Siddiqui-Bloch-Gastwirth variance estimate provided the smoothing parameter R-4 and following are piecewise linear, without discontinuities, but differ in how h is computed.

  2. In effect, the methods compute Qp, the estimate for the k-th q-quantile, where p = k/q, from a sample of size N by computing a real valued index h.
