This paper investigates the issue of determining dimensions row and column factor spaces in matrix-valued data. Exploiting eigen-gap spectrum sample second moment matrices data, we propose a family randomised tests to check whether one-way or two-way structure exists not. Our do not require any arbitrary thresholding on eigenvalues, can be applied with (virtually) no restrictions relative rate ...

abstract in order to evaluation the effects of price policies (wheat guarantee price in each period and its price lag), environmental (planted area) and climatic (min and max average temperature, total annual precipitation, cold-day degree and hot-day degree) factors, we considered wheat yield in razavi-khorasan province (9 cities) for a 13-year statistical period (1371-72 to 1383-84). in this ...

We discuss the detection limits and current status of a uniform survey of SDSS I for ultra-faint Milky Way dwarf galaxies. We present the properties of two new, low surface brightness Milky Way companions discovered as a result of this survey. One of these companions is the Ursa Major dwarf, the newest dwarf spheroidal companion to the Milky Way and the lowest luminosity galaxy yet known. Ursa ...

We present an algorithm for hashing αn elements into a table with n separate chains that requires O(1) deterministic worst-case insert time, and O(1) expected worst-case search time for constant α. We exploit the connection between two-way chaining and random graph theory in our techniques.

Suggested Running Head: Application of two-way RC in the assessment of hydrodynamic dispersion 2 ABSTRACT Zones of mixing between shallow groundwaters of different composition were unravelled by " two-way regionalized classification " , a technique based on Correspondence Analysis, Cluster Analysis and Discriminant Analysis, aided by gridding, map-overlay and contouring tools. The shallow groun...

We consider communication between two parties using a bipartite quantum operation, which constitutes the most general quantum mechanical model of two-party communication. We primarily focus on the simultaneous forward and backward communication of classical messages. For the case in which the two parties share unlimited prior entanglement, we give inner and outer bounds on the achievable rate r...
