A novel generalized ridge regression method for quantitative genetics.
As the molecular marker density grows, there is a strong need in both genome-wide association studies and genomic selection to fit models with a large number of parameters. Here we present a computationally efficient generalized ridge regression (RR) algorithm for situations in which the number of parameters largely exceeds the number of observations. The computationally demanding parts of the ...
متن کاملLoop ridge count differences 1 Loop ridge count differences between genders
The purpose of this study was to follow Acree’s 1999 theory and demonstrate that there are significant differences in the loop ridge count of male subjects compared to that of female subjects. This was based on the belief that women tend to have finer ridge detail, therefore more ridges, while men have coarse ridge detail, thereby fewer ridges [1]. This study, in contrast to Acree’s methodology...
متن کاملThe Current and Future Use of Ridge Regression for Prediction in Quantitative Genetics
In recent years, there has been a considerable amount of research on the use of regularization methods for inference and prediction in quantitative genetics. Such research mostly focuses on selection of markers and shrinkage of their effects. In this review paper, the use of ridge regression for prediction in quantitative genetics using single-nucleotide polymorphism data is discussed. In parti...
متن کاملLinkage Analysis of a Model Quantitative Trait in Humans: Finger Ridge Count Shows Significant Multivariate Linkage to 5q14.1
The finger ridge count (a measure of pattern size) is one of the most heritable complex traits studied in humans and has been considered a model human polygenic trait in quantitative genetic analysis. Here, we report the results of the first genome-wide linkage scan for finger ridge count in a sample of 2,114 offspring from 922 nuclear families. Both univariate linkage to the absolute ridge cou...
متن کاملDermatoglyphics and Schizophrenia: a meta-analysis and investigation of the impact of obstetric complications upon a-b ridge count.
BACKGROUND Patients with schizophrenia show deviances in their dermatoglyphics, in particular reductions in palmar a-b ridge counts (ABRCs), which are evidence of an early developmental deviance. However, the severity or the origin of these ABRC changes has not been established. METHOD (i) We examined the published literature on the ABRC in patients with schizophrenia against controls with a ...
