(HP-65) Incidence & Recovery Rates estimation
An extract from Estimation of incidence and recovery rates of Plasmodium falciparum parasitaemia from longitudinal data, Bull. World Health Organ., Vol. 54, 1976 pgs. 685-693

    A method is described of estimating the malaria incidence rate ĥ and the recovery rate r from longitudinal data. The method is based on the assumption that the phenomenon of patent parasitaemia can be represented by a reversible two-state catalytic model; it is applicable to all problems that can be represented by such a model.

… The derivation of these formulae is given in Annex 1, with a method for calculating the variance of the estimates. Annex 2 provides a programme for the computation of ĥ, … and t, using the Hewlett-Packard 65 pocket calculator

                                               Annex 2
                                  CALCULATOR PROGRAMME
  The formulae (3), (4) and (5) of Annex 1 were programmed for the Hewlett-Packard 65 pocket calculator.
