Homogeneity analysis using absolute deviations
Homogeneity analysis is a technique for making graphical representations of categorical multivariate data sets. Such data sets can also be represented by the adjacency matrix of a bipartite graph. Homogeneity analysis optimizes a weighted least-squares criterion and the optimal graph layout is computed by an alternating least squares algorithm. Heiser Comput. Statist. Data Anal. (1987) 337, loo...
متن کاملSTAT: Speech Transcription Analysis Tool
The Speech Transcription Analysis Tool (STAT) is an open source tool for aligning and comparing two phonetically transcribed texts of human speech. The output analysis is a parameterized set of phonological differences. These differences are based upon a selectable set of binary phonetic features such as [voice], [continuant], [high], etc. STAT was initially designed to provide sets of phonolog...
متن کاملA Regression Model for Multilevel Homogeneity Analysis
One of the basic techniques that analyzes categorical data is homogeneity analysis. The technique originated in the work of Guttman [17] as a method of scale construction using reciprocal averaging. Burt [5] described homogeneity analysis as a principal components analysis of qualitative data. Hayashi [19] stressed homogeneity analysis as one possible way of quantifying categories. It should be...
متن کاملHomogeneity and Stability in Conceptual Analysis
This work comes within the field of data analysis using Galois lattices. We consider ordinal, numerical single or interval data as well as data that consist on frequency/probability distributions on a finite set of categories. Data are represented and dealt with on a common framework, by defining a generalization operator that determines intents by intervals. In the case of distribution data, t...
متن کاملA Parallel Implementation of Homogeneity Analysis
Advancements in processor performance during the last decade, along with a growing commercial demand for high performance computing, has contributed to the proliferation of parallel processing [8]. One factor driving this demand is the increasing size of databases. In order to analyze such large databases, using sophisticated statistical techniques, statisticians may find themselves at a loss f...
