3. Impulse response of an ARMA(1, 1) process Let « follow ARMA (1, 1) process-that is, the sum of an AR(1) and MA(1) process: 2+=02t-1+Et+01Et-1 where {E} is white noise. (a) Write this in the form (L)xt = O(L)E for polynomials $(L) and O(L), being sure to specify the polynomials. (b) Assuming the roots of …
The current implementation for polynomials is a vector where the term of degree k is stored at position k + 1. This is good for dense polynomials (those with mostly nonzero coefficients) but our factoring algorithms rely heavily on manipulating sparse polynomials like a” – 1. Therefore, • Create a new type called PolynomialSparse that …
