What is the difference between probability and typicality in the Rotor-Gene ScreenClust HRM Software?
'Probability' is the likelihood or chance that a sample is a member of each available cluster. The combined probabilities of a single sample add up to 1.00.
'Typicality' in the Rotor-Gene ScreenClust HRM analysis is a measure of how well a sample fits into its assigned cluster. It can also be seen as a measure of how far away a sample is from the centre of the cluster. Typicality values range from 0 to 1, the higher the value the closer it is to the centre of its assigned cluster. If a sample has a typicality value of 0.5, it means that approximately half of all samples within that cluster will be closer to the centre and the other half will be further away. In reality, this might not be the case as small samples numbers can have skewed distributions.
