Methods Canopy fogging was used to sample beetles from 29 trees. The samples were statistically described using Schao and the Simpson diversity index D. Cluster analyses and multi-dimensional scaling (MDS) were performed. The taxonomic and guild structures of the Chilean coleopteran fauna were compared quantitatively with those found in other parts of the world using homogeneity chi-square and ...

Two symplectic numerical integration methods, of mean-square order 1 and 2 respectively, for a linear stochastic oscillator with two additive noises are constructed via the stochastic generating function approach and investigated. They are shown by numerical tests to be efficient and superior to non-symplectic numerical methods.

The Chi square test is a statistical test which measures the association between two categorical variables. A working knowledge of tests of this nature are important for the chiropractor and osteopath in order to be able to critically appraise the literature.

This paper proposes two algorithms for generating intonation from a mixed CART-HMM intonation model for speech synthesis. Based either on a Viterbi search or on the Expectation-Maximization algorithm, the two generation algorithms are analyzed in terms of likelihood and F0 Root Mean Square Error. Listening tests are performed to subjectively evaluate the quality of the generated intonation.

Exact distributions of generalized Chi-square and Fisher statistics are used to derive confidence intervals and significance tests for inferring on one or two scaling parameters, respectively, under non-standard assumptions w.r.t. the multivariate sample distribution. The latter may have convex or radially concave density level sets and heavy or light distribution centers and tails. Independent...
