Project Problem .

1. Based on the yield rates on Nov.15, 2019, let us develop another yield curve model applying the Nelson-Siegel parsimonious approximation specified as below. F(t) = B1 + (B2 + Ball At - Bge At (a) Find out four parameters including 81, 82, 8,, and A solving the below equation: 20 20 min E((t) - At)) = > =1
