Error bounds on multivariate Normal approximations for word count statistics

REA Auditado

Given a sequence S and a collection Ω of d words,
it is of interest in many applications to characterize the multivariate
distribution of the vector of counts
U = (N(S,w1), ..., N(S,wd)),
where N(S,w) is the number of times a word
w ∈ Ω appears in the sequence S. We obtain
an explicit bound on the error made when approximating the multivariate
distribution of U by the normal distribution, when the
underlying sequence is i.i.d. or first-order stationary Markov over a
finite alphabet.

An Integrated Supplier-Buyer Inventory Model with Conditionally Free Shipment under Permissible Delay in Payments

REA Auditado

It is well known that production, distribution, marketing, inventory control,
and financing all/each have a positive impact on the performance of a supply
chain. Despite the growing interest in the development of integrated inventory
models, the interactions between these elements of a supply chain may not be
efficiently included, resulting in a restricted supply chain model presentation.
To incorporate this phenomenon, a mathematical model that tackles the
interdependent relationships between these aforementioned elements is developed
in this paper.

Chances are good that Bhavya in Bangalore will read your next x-ray, or as Thomas Friedman learned first hand, “Grandma Betty in her bathrobe” will make your Jet Blue plane reservation from her Salt Lake City home. In “Globalization 3.0,” Friedman contends, people from far-flung places will become principal players in the marketplace.
