Gene expression data (20 genes for 120 samples) from the microarray experiments of mammalian eye tissue samples of Scheetz et al. (2006).
1 |
An object of class list
of length 2.
This data set contains 120 samples with 100 predictors (expanded from 20 genes using 5 basis B-splines, as described in Yang, Y. and Zou, H. (2015)).
A list with the following elements:
x |
a [120 x 100] matrix (expanded from a [120 x 20] matrix) giving the expression levels of 20 filtered genes for the 120 samples. Each row corresponds to a subject, each 5 consecutive columns to a grouped gene. |
y |
a numeric vector of length 120 giving expression level of gene TRIM32, which causes Bardet-Biedl syndrome. |
