Interactive Biplot Construction
We analyze and discuss how a generic software to produce biplot graphs should be designed. We describe a data structure appropriate to include the biplot description and we specify the algorithm(s) to be used for several biplot types. We discuss the options the software should offer to the user in two different environments. In a highly interactive environment the user should be able to specify...
متن کاملThe Construction of a Partial Least Squares Biplot
A graphical display of PLS regression of a data set is presented. Biplots in regression analysis has many advantages, including demonstrating the association between samples and variables graphically. The PLS biplot provides a single graphical representation of the samples alongside the predictor and response variables, as well as their interrelationships.
متن کاملInteractive Qualitative Model Construction
We describe our approach to support the construction of qualitative models used for predicting the behaviour of physical devices. Model speciication is the process of specifying the properties of a particular device at hand and specifying the domain knowledge needed to predict its behaviour. It can be supported by a set of dedicated editors. Model modiication is the process in which deviations ...
متن کاملInteractive Construction of EnCOrE
One of the major challenges of current ITS research is scaling up to real world learning scenarios. Another one, strictly interwoven, is to integrate human learning with other human activities, such as constructing theories or performing experiments, as it is the case in e-Science. The paper describes the results of the first phase of an ambitious project: EnCOrE for building and using an Encyc...
متن کاملThe Geometry of Biplot Scaling
A simple geometry allows the main properties of matrix approximations used in biplot displays to be developed. It establishes orthogonal components of an analysis of variance, from which different contributions to approximations may be assessed. Particular attention is paid to approximations that share the same singular vectors, in which case the solution space is a convex cone. Two and three-d...
