An Efficient Variable Selection Approach for Analyzing Designed Experiments
The analysis of experiments where a large number of potential variables are examined is driven by the principles of effect sparsity, effect hierarchy, and effect heredity. We propose an efficient variable selection strategy to specifically address the unique challenges faced by such analysis. The proposed methods are natural extensions of a general-purpose variable selection algorithm, LARS (Ef...
متن کاملVariable Selection for Gaussian Process Models in Computer Experiments
In many situations, simulation of complex phenomena requires a large number of inputs and is computationally expensive. Identifying the inputs which most impact the system so that these factors can be further investigated can be a critical step in the scientific endeavor. In computer experiments, it is common to use a Gaussian spatial process to model the output of the simulator. In this articl...
متن کاملRequirement of a conservative cytotoxicity assay selection in cellular experiments
Assessment of the cellular effects of natural and/or synthetic products is one of the major goals in biological experiments. This assessment may be conducted at different levels; cellular viability, cellular biological activity, and cellular structure and morphology. Different assays are available for any of above purposes. It is becoming of a routine exercise to apply any of these assays, and ...
متن کاملConcordance Measure-based Feature Screening and Variable Selection
The C-statistic, measuring the rank concordance between predictors and outcomes, has become a standard metric of predictive accuracy and is therefore a natural criterion for variable screening and selection. However, as the C-statistic is a step function, its optimization requires brute-force search, prohibiting its direct usage in the presence of high-dimensional predictors. We develop a smoot...
متن کاملOptimality of graphlet screening in high dimensional variable selection
Consider a linear model Y = Xβ + σz, where X has n rows and p columns and z ∼ N(0, In). We assume both p and n are large, including the case of p n. The unknown signal vector β is assumed to be sparse in the sense that only a small fraction of its components is nonzero. The goal is to identify such nonzero coordinates (i.e., variable selection). We are primarily interested in the regime where s...
