A-OPTIMAL RUN ORDERS WITH A LINEAR TREND

A-optimal ran orders are considered in the presence of a linear trend with emphasis on non-orthogonal situations where no trend-free run order can be. A-optimal. Some possibilities for further extension are also briefly indicated.     

Freighting English law: interpreting maritime spaces,law and the Armenian strategies in the Indian Ocean

In this article, I examine the formation of the English East India Company's legal regime in the Indian Ocean between the mid‐eighteenth and early nineteenth centuries. I look at how this process affected maritime trade and space from the vantage point of Armenian merchants' interactions with the colonial regime in the courts of law. The productive tensions arising from the colonial regime's new protocols and the merchants' leveraging tactics make for a complex story of Anglo‐Armenian dialogue. I argue that indigenous agency in the colonial courts complicated the binary colonial/indigenous structure. The idea of legal pluralism that emerges from the article suggests that the identity of an imperial subject or the definition of law was neither a given nor simply imposed through colonial coercion but was a complex product of a long‐term dialogue and rationalization.     

SOME SIMPLE APPROXIMATIONS FOR THE DOUBLY NONCENTRAL z DISTRIBUTION

We give two simple approximations for evaluating the cumulative probabilities of the doubly noncentral z distribution. These can easily be used for evaluating the cumulative probabilities of the doubly noncentral F distribution as well. We compare our results with those obtained by Tiku (1965) using series expansion. An industrial situation where a quality characteristic of interest follows the doubly noncentral z distribution is also cited. However, in this case the exact probabilities could be calculated using results on the ratio of two normal variables.
