摘要
对只有一个变点模型x(i/n)=f(i/n)+ε(i/n),其中,f(t)={J1+S1(t-t0),0<t≤t0,J2+S2(t-t0),t0<I≤1,ε(i/n),…,ε(n/n)独立同分布,J1,J2,S1,S2,t0为未知参数,讨论了变点t0处,跳变度(J2-J1)和坡变度(S2-S1)的联合分布。
For the change point model allowing at most one change x(i/n) =f(i/n)…, ε (n/n ) are independently and identically distributed, while J1,J2,S1,S2 and to are unknown paraments, the joint distribution of estimating the magnutude of jump (J2 -J1 ) and slope change (S2 -S1 ) at the change point to is discussed.
