## Abstract A new test for timeβdependent parameters is proposed. The __Trig__βtest is based on a trigonometric expansion to approximate the unknown functional form of the variation in the parameters concerned. It is shown to have the correct empirical size and excellent power to detect structural

β¦ Synopsis
We describe a test, based on the correlation integral, for the independence of a variable and a vector that can be used with serially dependent data. Monte Carlo simulations suggest that the test has good power to detect dependence in several models, performing nearly as well or better than the BDS test in univariate time series and complementing the BDS test in distributed lag models. Finally, we apply our test in conjunction with the BDS test to examine models of US unemployment rates.

We describe probabilistic primality tests applicable to integers whose prime factors are all congruent to 1 mod r where r is a positive integer; r = 2 is the Miller-Rabin test. We show that if Ξ½ rounds of our test do not find n = (r + 1) 2 composite, then n is prime with probability of error less th
This paper introduces a general or "distribution-free" model to analyze the lifetime of components under accelerated life testing. Unlike the accelerated failure time (AFT) models, the proposed model shares the advantage of being "distribution-free" with the proportional hazard (PH) model and overco
## Abstract In this paper we investigate properties of the general monotone sequences and functions, a generalization of monotone sequences and functions as well as of those of bounded variation. Some applications to various problems of analysis are given. Β© 2011 WILEYβVCH Verlag GmbH & Co. KGaA, W

Measurements of plasma homovanillic acid (HVA), plasma 3-methoxy-Chydroxyphenylglycol (MHPG), serum prolactin and Hamilton Depression Rating Scale (HDRS) scores were made in 21 cocaine-dependent patients seeking inpatient treatment. These measurements were obtained within 1-3 days of the last dose o
