A drop in dispersion, F -ratio like, permutation test (D) for linear quantile regression estimates (0 ≤ τ ≤ 1) had relative power ≥1 compared to quantile rank score tests (T ) for hypotheses on parameters other than the intercept. Power was compared for combinations of sample sizes (n = 20 − 300) and quantiles (τ = 0.50 − 0.99) where both tests maintained valid Type I error rates in simulations...

We prove that the quasi-score estimator in a mean-variance model is optimal in the class of (unbiased) linear score estimators, in the sense that the difference of the asymptotic covariance matrices of the linear score and quasi-score estimator is positive semi-definite. We also give conditions under which this difference is zero or under which it is positive definite. This result can be applie...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...

MOTIVATION In order to enhance genome annotation, the fully automatic fold recognition method GenTHREADER has been improved and benchmarked. The previous version of GenTHREADER consisted of a simple neural network which was trained to combine sequence alignment score, length information and energy potentials derived from threading into a single score representing the relationship between two pr...
