Early Stopping plot

Early Stopping

This document is a reference to the Early stopping RMarkdown file. Here, we present the results of conducting the combined 10 replicates of correlation for within-group 2 prediction (Within), cross-group prediction (Cross), and Early stopping (Early). The purpose was to validate the approach. Subsequently, a plot was generated, with each color representing a different replicate.

Load the data

• All_COR.RData is a data file that contains rows representing Within, Cross, and Early-stopping (with 100 stops- Early_1:100) correlation as well as columns representing different replicates.
