• Likelihood - likelihood is related to consultant terminologist work done by Rob Hausam.

• James R. Campbell proposed a hierarchy of "likelihood"-related property types, possibly descendants of the property type "Presence"
  
  • Probability (or likelihood, etc.) here is the probability of presence of an entity or occurrence of an event

• • Two distinct cases were identified:

    1. Specifying certainty (or uncertainty) about the result of an observation. Examples: Fetal sex, Trisomy 21 present by "Dosage of chromosome specific cf DNA" method.
    2. Prediction of a possible future event based on varying amount of information about the patient, from population-only based assessment (i.e. prevalence) to assessment based on several variables. Examples include 1p36 deletion risk based on population risk, Trisomy 21 risk based on maternal age, to the CHADS-VASC instrument
  Prediction vs. observation of current state may have different representations (disposition vs. "presence style")
  • Prediction (probability) of a future event based on observations of the current "state" , e.g. probability of future stroke, probability of trisomy 21 in fetus/child given maternal age only
  Probability of something being present at the time of observation, where the observation method cannot give 100 % (or approximately 100 %) certain results, e.g. probability of the biological sex (M/F) of a fetus, trisomy 21 probability of a fetus during pregnancy
  • 1. .

Example values:

• Review use cases for different "likelihood" observables
• Daniel Karlsson Test at least one solution to some of the cases found
