| In this article, we generalize the input{domain based software reliability measures by Nelson and by Weiss and Weyuker, introducing expected failure costs under the operational distribution as a measure for software unreliability. This approach incorporates in the reliability concept a distinction between diierent degrees of failure severity. It is shown how to estimate the proposed quantity ...

Much of the research for this paper also connects with the work of the ESRC funded NEXSUS project coordinated by Peter Allen. I am particularly grateful to Richard Nelson and an anonymous referee for their constructive and helpful comments on a previous draft. An insistent theme in Richard Nelson's work is that of 'capitalism as an engine of progress'. In this paper I explore this idea through ...

inverse sampling design is generally considered to be appropriate technique when the population is divided into two subpopulations, one of which contains only few units. in this paper, we derive the horvitz-thompson estimator for the population mean under inverse sampling designs, where subpopulation sizes are known. we then introduce an alternative unbiased estimator, corresponding to post-str...

Most biogeographers will probably agree with Ebach et al. (2003) that an essential goal of biogeography is to ‘discover why organisms are distributed the way they are today’ (citing Platnick & Nelson, 1978). Moreover, many also agree that this is achieved by uncovering ‘the patterns of spatial distribution attained by life on earth and the means by which these distributions were achieved’ (citi...

Consider a study where the times of occurrences of a recurrent event for n units are monitored. For the ith unit, T(i1), T(i2), …, denote the successive event interoccurrence times and this unit is monitored over a random period [0, τ(i)] with τ(i) independent of the T(ij)s. Over this monitoring period, [Formula: see text] is the random number of event occurrences. The T(ij)s are independent an...
