Concept Representation with Overlapping Feature Intervals
This article presents a new form of exemplar-based learning method, based on overlapping feature intervals. In this model, a concept is represented by a collection of overlappling intervals for each feature and class. Classificas . tion with Overlapping Feature Intervals COFI is a particular implementation of this technique. In this incremental, inductive, and supervised learning method, the ba...
متن کاملComparing treatment means: overlapping standard errors, overlapping confidence intervals, and tests of hypothesis
Little3 provided a conceptual history of significance tests and Stephens et al.4 documented its prevalence in ecology and evolution. Salsburg5 wrote that, ‘. . . hypothesis testing has become the most widely used statistical tool in scientific research,’ and Lehmann6 suggested that t and F tests of hypotheses ‘today still constitute the bread and butter of much of statistical practice.’ Critici...
متن کاملOverlapping confidence intervals or standard error intervals: What do they mean in terms of statistical significance?
We investigate the procedure of checking for overlap between confidence intervals or standard error intervals to draw conclusions regarding hypotheses about differences between population parameters. Mathematical expressions and algebraic manipulations are given, and computer simulations are performed to assess the usefulness of confidence and standard error intervals in this manner. We make re...
متن کاملContrasting Diversity Values: Statistical Inferences Based on Overlapping Confidence Intervals
Ecologists often contrast diversity (species richness and abundances) using tests for comparing means or indices. However, many popular software applications do not support performing standard inferential statistics for estimates of species richness and/or density. In this study we simulated the behavior of asymmetric log-normal confidence intervals and determined an interval level that mimics ...
متن کاملPrediction of genetic contributions and generation intervals in populations with overlapping generations under selection.
A method to predict long-term genetic contributions of ancestors to future generations is studied in detail for a population with overlapping generations under mass or sib index selection. An existing method provides insight into the mechanisms determining the flow of genes through selected populations, and takes account of selection by modeling the long-term genetic contribution as a linear re...
