In this paper we extend Rydberg-Shephards acivity, direction and size decomposition of trade-by-trade price movements to the mulvariate case. We illustrate our ideas using a bivariate modelling problem - modelling the evolution of the prices of Ford and GM shares. Throughout we use the...

For a {0, 1}-pattern of finite length, an empirical process is introduced in order to describe the number of overlapping occurrences of the pattern at each level t[set membership, variant][0,1] in a sequence of the corresponding indicators of i.i.d. [0, 1]-valued observations of length n. A...

Empirical-distribution-function (EDF) goodness-of-fit tests are considered for the beta-binomial model. The testing procedures based on EDF statistics are given. A Monte Carlo study is conducted to investigate the accuracy and power of the tests against various alternative distributions. Our...
