Ternary plots of independent data. Each point in a plot sums to a total of 100%. The three corners of the plot represent measurement locations of 100% malignant cells, 100% connective tissue, and 100% fat tissue. Points within the triangle represent mixtures of these substances. For each measurement location, the percentage of one of these substances decreases linearly with increasing distance from the corner that represents 100% of the substances. a Composition of the measurement locations. The size of the dots is proportional to the number of measurement locations with that specific tissue composition. b–e Classification model output of Model I–Model IV
