Explain what each of the four terms in the model are meant to measure.

In the Svensson (1994) model of the term structure of interest rates r(t) = + (1e ) / ,t + , (((1 e, ) / 2,t) e^) Ot 2t -22. + 31 ((( e ) / 2,5) - e-^2,) 3t Where rt (T) is the interest rate at time t of maturity 7 Bot, B1, B2t and B3t are estimated parameters At and A2t are decay parameters.
