WebMay 28, 2008 · The data consist of n=13 binary sequences with an outcome y=1 for a recorded LOH at a given SNP, and a 0 otherwise. Each sequence is of length 116204. The primary objective of this study is the identification of regions of increased LOH, i.e. the main event of interest is a property of regions of SNPs. Consequently, we divide the LOH … WebMar 16, 2024 · The BKMR framework is a flexible nonparametric approach that allows the estimation of the overall effect estimate of multiple correlated exposures accounting for confounding variables. 49 The method was implemented with the R package “bkmr” using 10,000 iterations. 50 All variables were included in the model using the variable selection …
