The PSA dynamics of the best responder patient for different values of α and β.

For the case α = 1/3, β = 1/3 the PSA represents an average of the three populations, for the case α = 1, β = 0, the PSA mesures only the T⁺, for the case α = 0, β = 1 it measures the T^P, while for the case α = 0, β = 0 it corresponds to the T⁻.
