THE ALGEBRAIC AND STATISTICAL TRACTABILITY OF THE CITY BLOCK METRIC
British Journal of Mathematical and Statistical Psychology, 1973If the within‐dimensional ranks of the points are known, the equation defining a city block distance can be transformed into a linear equation with +1, −1 and 0 as coefficients. This transformation permits the common least‐squares solution for the coordinates as well as the application of regression analysis with the possibility of testing for ...

Research of statistical safety of stochastic transformation blocks
2018 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2018This paper is devoted to the issues of improving the quality of information protection algorithms by using blocks of stochastic transformation or R-blocks. The principles of R-blocks building are considered, as well as examples of their using in the construction of block and streaming algorithms for information encryption.

Statistical versus optimal partitioning for block entropies
Kybernetes, 2013PurposeGiven a time‐series, what is the best partitioning of the state space in order to obtain reasonable values for the block entropies? The purpose of this paper is to provide a simple answer (an algorithm), although approximative, in connection with symbolic dynamics and statistical properties of 1‐d maps on the interval.Design/methodology ...

A Blocked Statistics Method Based on Directional Derivative
2012The basic idea of identifying the motion blurred direction using the directional derivative is that the original image be an isotropic first-order Markov random process. However, the real effect of this method is not always good. There are many reasons, of which the main is that a lot of pictures do not meet the physical premises. The shapes of objects

22 Block designs: Their combinatorial and statistical properties
1996Publisher Summary This chapter discusses the combinatorial and statistical properties of block designs. The theory of discrete designs is intimately related to many other areas of combinatorial theory. Block designs have opened up many interesting and challenging problems in combinatorial mathematics. The fundamental problems related to block designs,

Some Statistical Properties of Nested Block Designs
1998Nested block designs in a wide sense are newly discussed from a statistical point of view. Some statistical properties of such designs are presented with some constructions. The corresponding properties of the usual nested block designs in the literature are included as a special case.
