Handle RepeatedKFold #15
Description
RepeatedKFold runs without errors, however, the scatter plots in the HTML report and the predictions in the cv_predictions.csv file are not aggregated across repeats. This means that for every sample (e.g. person) in the data, we get as many predictions as there are repeats. We want to aggregate across repeats for every sample. This is what we want to plot in the scatter plot in the end. The same thing goes for the network strengths we want to save and plot. We need to figure out how to know the repeats per sample so that we can aggregate over all repeats.
