Without loss of generality, v and [Z.sub.k])([y.sub.k]) are independent; thus, the probability density function of I([y.sub.k]) can be calculated as

Mathematically, let [mathematical expression not reproducible] and [mathematical expression not reproducible], where F is the cumulative function of the probability density function f(y; [mu], [THETA]); then the randomized quantile residuals for [y.sub.i] are
The calculated results show that the probability density function model (PDFM) more accurately reflects measurement data than the log-law model.
