Witt's book gave tables based on 10% (the ...
Define the "reverse time" variable z = T − t.(t = 0, z = T and t = T, z = 0).Then: Plotted on a time axis normalized to system time constant (τ = 1/r years and τ = RC seconds respectively) the mortgage balance function in a CRM (green) is a mirror image of the step response curve for an RC circuit (blue).The vertical axis is normalized to system asymptote i.e. perpetuity value M a /r for ...
