A randomly selected 70%% and the remainder of the samples were taken for training and testing respectively.
In this model (called Model 1-1), the data was divided by taking the first 70%% and the remainder of the samples for training and testing respectively.
In fact, as discussed in the previous smoker example, features are likely to be multi modal with some modes having very low representation in the sampled dataset, but within those modes prevalence of one class may be significantly different from that for the remainder of the samples.
The remainder of the samples was captured through the biotinylated proteins by adding 20 µL of a 20% slurry of monomeric Avidin beads and shaking for ten minutes.
Except for clones numbered 25 and 26, the remainder of the samples were either unmethylated or were methylated at only two positions.
Characteristic for a distinct outlier gene is the observation that one subgroup of samples showed very strong and uniform staining, while the remainder of the samples only showed very weak or negative staining, similar to the normal expression of this gene in non-malignant, control samples.
