Effect size estimates and standard errors obtained from gene expression measurements on 7129 genes across 49 samples.
data(bcwest)A data frame with 7129 observations on the following 2 variables.
estimatesa vector of effect size estimates
std.errstandard errors associated with effect size estimates
A description of the original data may be found in West et al. (2001). For each gene, the effect size estimate was computed from the difference in the mean expression levels of the two groups (i.e., mean(bc-positive group) - mean(bc-negative group)).
