An Improved Approximation to the Estimation of the Critical F Values in Best Subset Regression
Variable selection methods are routinely applied in regression modeling to identify a small number of descriptors which "best" explain the variation in the response variable. Most statistical packages that perform regression have some form of stepping algorithm that can be used in this identification process. Unfortunately, when a subset of p variables measured on a sample of n objects are sele...
متن کاملComputational strategies for deriving the best-subset regression models
Riassunto: An efficient branch-and-bound algorithm for computing the best-subset regression models is proposed. The algorithm avoids the computation of the whole regression tree that generates all possible subset models. It is formally shown that if the branch-and-bound test holds, then the current subtree together with its right-hand side subtrees are cut. This reduces significantly the comput...
متن کاملReference Values for Serum Lipid Profiles in Iranian Adults: A Spline-Based Quantile Regression Method
Background: Reference measurements are used to screen for abnormal blood lipids. The problem is that these reference values obtained in one population cannot be effective for another population. This study aimed to determine the reference values for blood lipids profiles in the population aged 25-64 years in Yazd. Methods: This descriptive study was based on the data of Yazd Health Study (YaHS...

متن کاملReference Values for Serum Total Cholesterol Concentrations Using Percentile Regression Model: A Population Study in Mashhad
Background and Purpose: Serum total cholesterol (TC) concentrations are affected by several factors including ethnicity, diet, geographic, and environmental determinants, and are related to another disease, including hypothyroidism, and renal and liver disease. It is associated with an increased risk of cardiovascular disease, particularly if associated with high levels of serum low-density lip...
