Statistical comparison of additive regression tree methods on ecological grassland data

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

On Regression-Tree-Based Synthetic Data Methods for Business Data

The challenge of balancing the competing objectives of allowing statistical analysis of confidential data and maintaining confidentiality is of great interest to national statistical agencies and other data custodians seeking to make their data available for research. This balance is often characterised as a trade-off between disclosure risk and data utility, where disclosure risk attempts to c...

Data Classification based on Decision Tree, Rule Generation, Bayes and Statistical Methods: An Empirical Comparison

In this paper, twenty well known data mining classification methods are applied on ten UCI machine learning medical datasets and the performance of various classification methods are empirically compared while varying the number of categorical and numeric attributes, the types of attributes and the number of instances in datasets. In the performance study, Classification Accuracy (CA), Root Mea...

Comparison of regression tree data mining methods for prediction of mortality in head injury

With this research, we sought to examine the performance of six different regression tree data mining methods to predict mortality in head injury. Using a data set consisting of 1603 head injury cases, we assessed the performance of: the Classification and Regression Trees (CART) method; the Chi-squared Automatic Interaction Detector (CHAID) method; the Exhaustive CHAID (E-CHAID) method; the Qu...
