Let T denote the lifelength of a component, the distribution of which, conditional on a parameter y, is known. It is supposed that y is a realization of nonnegative stochastic process {Y,t[greater-or-equal, slanted]0}, reflecting random variation in the environment in which the component is...

Bounds on the uniform distance between a [chi]22n distribution and the distribution of 2[Sigma]ni = 1 Xi/[mu], where X1, X2,..., Xn are n independent, identically distributed nonnegative random variables with common mean [mu], are derived assuming that the Xi's are HNBUE or HNWUE or that a...

Consider the flow of probability density functions generated by the sequence of iterations of a dynamical map on a differentiable manifold. It is shown that, under a simple condition on the dynamical map, the corresponding sequence of random variables is stochastically monotone for any initial...

Consider a binary coherent system of nonrepairable components, the lifelength distributions of which lie in the single parameter exponential family of distributions. Given observations of the lifelengths of the constituent components, it is shown how inversion of the likelihood ratio test can be...

The authors estimated air quality impacts due to residential firewood use for the year 2000 for 16 U.S. metropolitan areas. The wood usage estimates were based on price elasticities in relation to other space heating fuels, a range of future firewood prices, and an algorithm for the spatial...
