Different detection summaries?

[afmagee42]

          I think this also highlights that perhaps what we really want, with respect to some of the discussion in #33, is to have 5 summaries, or maybe 6:

• Pr(index detected) (this is just the passive detection probability, accounting for the delay)
• Pr(non-index detected)
• Pr(non-index detected actively)
• Pr(non-index detected pasively)
• Pr(any case detected before it's infectious)
  • If 6 summaries, this is two: Pr(index case detected before it's infectious) and Pr(non-index case detected before it's infectious)
