A large collection of factorial data analysis methods can be characterized by the following matrices: X, the k x n matrix of data, and A, B the symmetric positive definite matrices of size n, k which represent the chosen norms of ℝn, ℝk, respectively. All methods amount to computing the largest...
The analysis of variance (ANOVA) is widely used in biological studies, yet there remains considerable confusion among researchers about the interpretation of hypotheses being tested. Ambiguities arise when statistical designs are unbalanced, and in particular when not all combinations of design...
In medical applications of survival analysis we are often interested in determining prognosis, and the adoption of statistical models in the establishment of a prognostic index has become common practice. The aim of this presentation is to examine the problem of re‐evaluation or the modification...
The second part of this paper deals with the systolic implementation of the computational kernel for factorial data analysis, defined in Part I, on special‐purpose hardware. The framework of the study is that a sequence of different algorithms has to be performed on a unique hardware array. This...
In this paper we present an original top‐down hierarchical classification algorithm. In our approach we associate to each decomposition a ‘degree of separability’ which is used to evaluate the efficiency of the decomposition. In particular, it shows whether or not the classes are well separated...
The problem of choosing strategies which minimize the cost of decision tree testing is considered in the case where the cost of each test depends on its outcome. The classical entropy bound on the cost is derived and we propose an algorithm for decision tree design based on an extension of...
