More specifically, the red and blue lines on the charts represent specific measures of the parameter vectors both within and between chains. For the results to be sensible, these should be relatively constant (although there will always be some variation) and they should converge. Dynare reports three measures: “interval”, being constructed from an 80% confidence inter- val around the parameter mean, “m2”, being a measure of the variance and “m3” based on third moments. In each case, Dynare reports both the within and the between chains measures. The figure entitled “multivariate diagnos- tic” presents results of the same nature, except that they reflect an aggregate measure based on the eigenvalues of the variance-covariance matrix of each parameter.
帮你插了一下dynare的手册，自行参考吧

非常感谢~~  看书不仔细{:3_42:}

可不可以再问你可以问题呀，DYNARE模拟出来的脉冲响应图的灰色带是95%的置信区间么？

默认设置的话脉冲反映函数的图好像不显示区间的，具体可以设置的吧，你查查手册吧，我没怎么注意过这个问题
