Apa perbedaan antara model deterministik dan stokastik?
Model Linier Sederhana: x = α t + ϵtx=αt+ϵtx=\alpha t + \epsilon_t mana ~ iid N ( 0 , σ 2 )ϵtϵt\epsilon_tN( 0 , σ2)N(0,σ2)N(0,\sigma^2) dengan danV a r ( x ) = σ 2E( x ) = α tE(x)=αtE(x) = \alpha tVa r ( x ) = σ2Var(x)=σ2Var(x)=\sigma^2 AR (1): Xt= α Xt - 1+ ϵtXt=αXt−1+ϵtX_t =\alpha X_{t-1} +...
