A Markov chain is associated to a finite order one-sided moving average of a discrete time stationary Gaussian process. A
method is developed to specify thresholds for given on target significant levels in the sense that in the long run the probability that the moving average process lies in [L
i
, L
i+1), will be π
i
, i = 0,. . . ,m. Special inputs, AR(1) and MA(1) are treated in details. This article extends the work of Soltani et al. in (Commun Stat
Theory Methods 36(14):2595–2606) where the inputs were assumed to be i.i.d.; and a single threshold was considered.

Summary The practical elicitation of expert beliefs about logistic regression models is considered. An experiment is reported in which
ecologists quantified their prior beliefs about the relationship between various environmental attributes and the habitat
distribution of certain rare and endangered fauna. Prior distributions were elicited from the ecologists and combined with
sample data to form posterior distributions. The elicitation method was proposed by Garthwaite and Al-Awadhi (2004) and is
implemented through an interactive graphical computer program. Classical stepwise logistic regression and alternative forms
of prior distribution are compared using cross validation. Data on the environmental attributes have been mapped and stored
in a GIS database and the posterior distributions can be used to predict the probability of a species' presence/absence at
any site in the database. 相似文献

Six analogues and derivatives (1–6) of 3-phenylhydrazonopentane-2,4-dione (7) were subjected to gas-phase thermolysis. The Arrhenius log A (s−1) and Ea (kJ mol−1) of the analogues (1–5) are, respectively: 10.42 and 140.8 for 1-cyano-1-phenyl-hydrazonopropanone (1) , 11.19 and 135.4 for 1-cyano-1-( -nitrophenylhydrazono)-propanone (2) , 10.68 and 144.9 for 1-cyano-1-( -methoxyphenylhydrazono)propanone (3) , 11.76 and 137.8 for 1-cyano-3-phenyl-1-phenylhydrazonopropanone (4) , and 11.29 and 145.9 for 1-cyano-1-phenylhydrazonobutanone (5) . The corresponding values for ethyl 3-oxo-2-phenylhydrazonobutanoate (6) are 11.90 s−1 and 143.3 kJ mol−1. The rates of reaction at 600 K are compared with those of the title diketone (7) and of pentane-2,4-dione (8) and rationalized in terms of a plausible elimination pathway involving a semiconcerted six-membered transition state. © 1998 John Wiley & Sons, Inc.

In this paper we provide exact formula for the commute times of random walks on spherically symmetric random trees. Using this formula we sharpen some of the results presented in Al-Awadhi et al. to the form of equalities rather than inequalities. 相似文献
