Regression trees are used when the dependent variable has ordered discrete or continuous values, and the prediction error is commonly expressed as the square root of the difference between the observed and predicted values. The baseline will define what is “normal” for that person and will raise...

In this paper we propose a robust simple linear regression method, namely the smooth adaptwe line (SAL), which divides the data set into three equal groups on the basis of the ordered values of the explanatory variable. The estimators of the slope and intercept are obtained by using the ...
predictive mean matching (pmm) is utilized for numeric variables, logistic regression (logreg) for factor variables with two levels, multinomial logit model (polyreg) for factor variables with more than two levels, and ordered logit model (polr) for ordered variables...
Feature selection theory based on the Wilcoxon rank-sum test has been proposed to study lung and prostate cancers [7]. For ordered alternatives, the Jonckheere-Terpstra (JT) test [8, 9] is a nonparametric counterpart to the simple linear regression model. The JT test is used to assess ...
Robustness in folding mechanism modulates the kinetically dependent processes in catalysis, inhibition, and regulation, which proceed in ordered steps, and moderates harmful phenomena like misfolding and aggregation (11). Aspects of this robustness have been well studied and are substantiated by ...

The method combines information criteria, regression modeling and artificial neural networks. The paper also discusses simulation research related to efficiency assessment of the chosen variable selection methods and its application in the newly developed forecasting method. The assessment of this method is...
