Yeast cis-QTL Gene Regulatory Network Dataset
Description
The dataset (Y,X) are two matrices each with 3380 rows and 112 columns as described in the Vignettee "Elastic Net Enabled Sparse-Aware Maximum Likelihood for Structural Equation Models in Inferring Gene Regulatory Networks".
The Yeast expression trait data set was obatained from Brem R.B. and Kruglyak L (2005), and has been screened through:
1. screen and keep the ORF names in Kellis's ORF list (Kellis M et al, 2003);
2. screen out ORF with more than 5% of missing expression date;
3. perform eQTL mapping by Wilcoxon test, adjust by qvalue; keep the top one cisQTL;
4. fill in zeros for ORF without cisQTL in matrix X
Usage
data(yeast)Format
The format is matrix.
