regression trees.

The

regression tree is composed of 11 nodes, six of which are terminal nodes (Table).

Approaches that are applicable to cost estimation range from statistics based multivariable regression analysis to machine-learning techniques such as Classification and

Regression Trees (CART), M5 model tree (M5-MT), Artificial Neu ral Network (ANN), Support Vector Machines (SVM), and Least Squares Support Vector Machine (LS-SVM).

A

regression tree using distance from the Rio Grande and maximum depth explained 34% of the variation in abundance of N.

We explored 2 different predictive modeling approaches using past survey counts as the response data: 1) we fit a Poisson regression model with linear and additive effects of land-cover variables (on the log scale); 2) we formed predictions using boosted

regression trees (hereafter 'boosted trees'), a non-parametric method that tends to perform well in settings where interactions are prevalent or the relationship between response and predictor variables is highly non-linear (De'ath 2007, Elith et al.

Nonlinear

regression tree analysis was used to investigate nonlinear effects of site, strain, and environmental conditions (mean seasonal temperature and salinity).

The purpose of this study is to explore the performance of credit scoring using discriminant analysis, logistic regression, neural networks and classification and

regression tree.

We first performed a classification and

regression tree (CART) analysis using AnswerTree SPSS[R] version 3.

A RandomForest

regression tree analysis was performed (using the RandomForest algorithm in R (Prasad and others 2006)) on the total number of exit holes, epicormic shoots, and canopy transmission against the ATHI value.

The purpose of this study was to analyze characteristics of prisoners who engaged in high-risk behaviors prior to incarceration using classification and

regression tree analysis in order to identify groups at varying levels of HIV risk behaviors.

Hence, the data used to build the classification and

regression tree is either in the form of binned data or nominal data.

The expanded MDR method involves classification into two groups using a

regression tree, i.
