使用Uhlig线性化后，画出的究竟是谁的图像？
例如Yt*=lnYt-lnYss,线性化后，Dynare画的是Yt的图像，还是Yt*的图像，代码如下：



var Y I C R K W L A ;
varexo e;
parameters sigma phi alpha beta delta rhoa;
sigma = 2;
phi = 1.5;
alpha = 0.35;
beta = 0.985;
delta = 0.025;
rhoa = 0.95;
model(linear);
#Pss = 1;
#Rss = Pss*((1/beta)-(1-delta));
#Wss = (1-alpha)*(Pss^(1/(1-alpha)))*((alpha/Rss)^(alpha/(1-alpha)));
#Yss = ((Rss/(Rss-delta*alpha))^(sigma/(sigma+phi)))
*(((1-alpha)^(-phi))*((Wss/Pss)^(1+phi)))^(1/(sigma+phi));
#Kss = alpha*(Yss/Rss/Pss);
#Iss = delta*Kss;
#Css = Yss - Iss;
#Lss = (1-alpha)*(Yss/Wss/Pss);
//1-Labor supply
sigma*C + phi*L = W;
//2-Euler equation
(sigma/beta)*(C(+1)-C)=Rss*R(+1);
//3-Law of motion of capital
K = (1-delta)*K(-1)+delta*I;
//4-Production function
Y = A + alpha*K(-1) + (1-alpha)*L;
//5-Demand for capital
R = Y - K(-1);
//6-Demand for labor
W = Y - L;
//7-Equilibrium condition
Yss*Y = Css*C + Iss*I;
//8-Productivity shock
A = rhoa*A(-1) + e;
end;
